Get manga info from tracker (#1271)

* Barebones setup (only AniList works)

* Show tracker selection dialog when entry has more than one tracker

* MangaUpdates implementation

* Add logging and toast on error.

* MyAnimeList implementation

* Kitsu implementation

* Fix MAL authors and artists

* Decode AL description

* Throw NotImplementedError instead of returning null

* Use logcat from LogcatExtensions

* Replace strings with MR strings

* Missed a string

* Delete unused Author class.

* Add Bangumi & Shikimori support for info edit (#2)

This adds the necessary API calls and DTOs to allow for editing an
entry's data to the data from a tracker, specifically adding support
for Bangumi and Shikimori.

* Exclude enhanced trackers from tracker select dialog

* MdList implementation

* Remember getTracks and trackerManager
