Various fixes:

- Fix PresentationManager importer to take weird XML into account
- Fix OpenLP importer to support author_types
- Fix opening the data folder in KDE where it was being misinterpreted as a SMB share
- Fix a problem with the media player no longer controlling the playlist
- Fix a problem where a timer would expire after the application had been torn down
- Fix song database upgrades by moving upgrades 4 and 5 into 6 and writing some damage control
- Add a CHANGELOG.rst file

+OpenLP 2.4.6
+============
+
+* Fixed a bug where the author type upgrade was being ignore because it was looking at the wrong table
+* Fixed a bug where the songs_songbooks table was not being created because the if expression was the wrong way round
+* Changed the songs_songbooks migration SQL slightly to take into account a bug that has (hopefully) been fixed
+* Sometimes the timer goes off as OpenLP is shutting down, and the application has already been deleted (reported via support system)
+* Fix opening the data folder (KDE thought the old way was an SMB share)
+* Fix a problem with the new QMediaPlayer not controlling the playlist anymore
+* Added importing of author types to the OpenLP 2 song importer
