Vulnerability changelog

A transitional release, including new doc system.

- `is_typeclass(obj (Object), exact (bool))` now defaults to exact=False
- `py` command now reroutes stdout to output results in-game client. `py`
without arguments starts a full interactive Python console.
- Webclient default to a single input pane instead of two. Now defaults to no help-popup.
- Webclient fix of prompt display
- Webclient multimedia support for relaying images, video and sounds via
`.msg(image=URL)`, `.msg(video=URL)`
and `.msg(audio=URL)`
- Add Spanish translation (fermuch)
- Expand `GLOBAL_SCRIPTS` container to always start scripts and to include all
global scripts regardless of how they were created.
- Change settings to always use lists instead of tuples, to make mutable
settings easier to add to. (1912)
- Make new `CHANNEL_MUDINFO` setting for specifying the mudinfo channel
- Make `CHANNEL_CONNECTINFO` take full channel definition
- Make `DEFAULT_CHANNELS` list auto-create channels missing at reload
- Webclient `ANSI->HTML` parser updated. Webclient line width changed from 1.6em to 1.1em
to better make ANSI graphics look the same as for third-party clients
- `AttributeHandler.get(return_list=True)` will return `[]` if there are no
Attributes instead of `[None]`.
- Remove `pillow` requirement (install especially if using imagefield)
- Add Simplified Korean translation (aceamro)
- Show warning on `start -l` if settings contains values unsafe for production.
- Make code auto-formatted with Black.
- Make default `set` command able to edit nested structures (PR by Aaron McMillan)
- Allow running Evennia test suite from core repo with `make test`.
- Return `store_key` from `TickerHandler.add` and add `store_key` as a kwarg to
the `TickerHandler.remove` method. This makes it easier to manage tickers.
- EvMore auto-justify now defaults to False since this works better with all types
of texts (such as tables). New `justify` bool. Old `justify_kwargs` remains
but is now only used to pass extra kwargs into the justify function.
- EvMore `text` argument can now also be a list or a queryset. Querysets will be
sliced to only return the required data per page.
- Improve performance of `find` and `objects` commands on large data sets (strikaco)
- New `CHANNEL_HANDLER_CLASS` setting allows for replacing the ChannelHandler entirely.
- Made `py` interactive mode support regular quit() and more verbose.
- Made `Account.options.get` accept `default=None` kwarg to mimic other uses of get. Set
the new `raise_exception` boolean if ranting to raise KeyError on a missing key.
- Moved behavior of unmodified `Command` and `MuxCommand` `.func()` to new
`.get_command_info()` method for easier overloading and access. (Volund)
- Removed unused `CYCLE_LOGFILES` setting. Added `SERVER_LOG_DAY_ROTATION`
and `SERVER_LOG_MAX_SIZE` (and equivalent for PORTAL) to control log rotation.
- Addded `inside_rec` lockfunc - if room is locked, the normal `inside()` lockfunc will
fail e.g. for your inventory objs (since their loc is you), whereas this will pass.
- RPSystem contrib's CmdRecog will now list all recogs if no arg is given. Also multiple
bugfixes.
- Remove `dummyexample.com` as a default account email when unset, a string is no longer
required by Django.
- Fixes to `spawn`, make updating an existing prototype/object work better. Add `/raw` switch
to `spawn` command to extract the raw prototype dict for manual editing.
- `list_to_string` is now `iter_to_string` (but old name still works as legacy alias). It will
now accept any input, including generators and single values.
- EvTable should now correctly handle columns with wider asian-characters in them.
- Update Twisted requirement to >=2.3.0 to close security vulnerability
- Add `$random` inlinefunc, supports minval,maxval arguments that can be ints and floats.
- Add `evennia.utils.inlinefuncs.raw(<str>)` as a helper to escape inlinefuncs in a string.
- Make CmdGet/Drop/Give give proper error if `obj.move_to` returns `False`.
- Make `Object/Room/Exit.create`'s `account` argument optional. If not given, will set perms
to that of the object itself (along with normal Admin/Dev permission).
- Make `INLINEFUNC_STACK_MAXSIZE` default visible in `settings_default.py`.
- Change how `ic` finds puppets; non-priveleged users will use `_playable_characters` list as
candidates, Builders+ will use list, local search and only global search if no match found.
- Make `cmd.at_post_cmd()` always run after `cmd.func()`, even when the latter uses delays
with yield.
- `EvMore` support for db queries and django paginators as well as easier to override for custom
pagination (e.g. to create EvTables for every page instead of splitting one table).
- New `EvMore` methods `.init_pages`, `paginator` and `page_formatter` for easily customize pagination.
- Using `EvMore pagination`, dramatically improves performance of `spawn/list` and `scripts` listings
(100x speed increase for displaying 1000+ prototypes/scripts).
- `EvMenu` now uses the more logically named `.ndb._evmenu` instead of `.ndb._menutree` to store itself.
Both still work for backward compatibility, but `_menutree` is deprecated.
- `EvMenu.msg(txt)` added as a central place to send text to the user, makes it easier to override.
Default `EvMenu.msg` sends with OOB type="menu" for use with OOB and webclient pane-redirects.
- New EvMenu templating system for quickly building simpler EvMenus without as much code.
- Add `Command.client_height()` method to match existing `.client_width` (stricako)
- Include more Web-client info in `session.protocol_flags`.
- Fixes in multi-match situations - don't allow finding/listing multimatches for 3-box when
only two boxes in location.
- Made the `evennia` dir possible to use without gamedir for purpose of doc generation.
