Django-redisboard

------------------

* Added ``--version`` CLI option.
* Changed redisboard CLI admin header to show version and also fixed incorrect context that prevented AdminSite customizations overriding
said header. Probably view site link also fixed.

------------------

* Fixed incorrect settings loading of ``REDISBOARD_DETAIL_CONVERTERS``.

------------------

* Dropped support for Python 3.6.
* Overhauled internals to support customization of redis queries, deserialization and display using custom classes.
For that purpose there are new settings: ``REDISBOARD_DECODER_CLASS``, ``REDISBOARD_DISPLAY_CLASS``, ``REDISBOARD_VALUE_QUERY_CLASS`` and
``REDISBOARD_LENGTH_QUERY_CLASS``.
* Fixed various issues with pagination by simplifying it and making the use of cursors transparent to the user.
For this purpose the ``sampling_size`` and ``sampling_threshold`` models fields have been removed, and the ``REDISBOARD_ITEMS_PER_PAGE``
was removed and replaced with ``REDISBOARD_SCAN_COUNT`` and ``REDISBOARD_STRING_PAGINATION``.
* Added new setting ``REDISBOARD_DETAIL_CONVERTERS`` for customizing display of server details somewhat.
* Added new setting ``REDISBOARD_SLOWLOG_NUM`` option for limiting the slowlow displayed.
* The default value for the ``REDISBOARD_DETAIL_FILTERS`` setting was changed.
* Better connection management was implemented, both via render callbacks and ``__del__`` (as a fallback).
There shouldn't be any connection leaks anymore. If the DEBUG setting is True then warnings
will be issued should any connection be closed via ``__del__``.
* Added the ``--debug`` (to enable DEBUG and autoreload) and ``--decoder`` (to load a different data decoder) in the ``redisboard`` CLI.

------------------

* Fixed ``--password`` killing the django session (it won't change the password and invalidate session if it's identical).
* Fixed some alignment regressions in the table cells.

------------------

* Removed some of the more expensive and frankly pointless stats computations.
* Fixed internal error that occurred for empty databases.
* Cleaned up more code (hopefully all the Python 2 is all gone now).
* Changed the inspect page to include all the stats from the changelist.
* Changed the stats display to use tables instead of definition lists.
* Changed the ``--password`` CLI option to update the password regardless if the local sqlite was created or not.

------------------

* Replaced the hostname/port fields with an url field.
This allow SSL connection and whatever Redis will have in the future.
* Removed more dead code.
