===================
- Full rework of project! Import is now
``from easysettings.app import AppSettings`` (but left importable from
``easysettings`` for better backwards compatibility).
- Removed isolated settings functionality, unnecessary with a separate settings
module for tests and/or use of the ``TestCase.settings()`` context manager.
- Added ``easysettings.legacy.LegacyAppSettings`` for providing backwards
compatibility for prefixed project settings when moving settings to a
dictionary rather than individual settings with the same prefix.
