Arrnounced

Pagination
The web interface now allows you to list older announcements and snatches.

Announcements with optional groups
Announcements with optional groups are now handled. This affects for example AR and BTN.

Minor bug fixes
Some other more or less unnoticeable bug fixes are also included.

Mostly corrections of bugs, spelling and formatting.

As Python's standard library XML parser implementation is vulnerable to maliciously constructed data the implementation now uses [defusedxml](https://pypi.org/project/defusedxml/).

Multiline patterns
This release brings support for [multiline patterns](https://github.com/autodl-community/autodl-trackers/blob/cf392143eff916971d0627aa5827e4bc28bf8aad/trackers/AceHD.tracker#L47).

New database design
The database design is [updated](https://github.com/weannounce/arrnounced/commit/ef931eef27348f82254d601f96d094a7b9f147bb). The new design preserves the relation between an announcement and whether it was snatched.

If you used Arrnounced prior to this or used one of its predecessors you have two
options.
* Convert your old database using [convert_db.py](https://github.com/weannounce/arrnounced/blob/master/convert_db.py)
* Move the old database file for safe keeping.

The database file is called `brain.db` and Arrnounced keep it in `~/.arrnounced`

Re-notify backend of announcement
The ability to notify Sonarr/Radarr/Lidarr (backends) of an announcement via the web interface was broken for a while. It is now fixed. The notify interface is also changed to notify one of the configured backends. Not only the once configured for the specific tracker in your configuration file.

Issue solved where multiple servers, channels and announcers in the trackers files where handles as one. With this issue solved there were some changes to the configuration.

Field name changes:

Old | New
------|-------
nick | irc_nickname
nick_pass | irc_ident_password
tls | irc_tls
tls_verify | irc_tls_verify
inviter | irc_inviter
invite_cmd | irc_invite_cmd
delay | announce_delay

`irc_port` is now mandatory.

Mandatory fields `irc_server` and `irc_channels` are added.

`irc_channels` is a comma separated list of channels which will be joined on startup unless invite command has been configured.

* Support single line pattern tracker announcements from autodl-trackers
* Replace web UI auth with in page form
* Make web UI authentication optional
* Move default configuration and data to ~/.arrnounced
