Added KOTO_IS_CARTOGRAPHER macro and added that type check across all cartographer functions. Added more type checks and dropped use of g_object_get for UUIDs where possible.
Implemented koto_album_get_uuid function to be on parity with other structs like Artist, Playlist, Track.
Fix the displaying of discs and tracks in an album on initial index due to missing cartographer add track call.
Cleanup lots of double empty newlines. Updated ptr spacing in uncrustify config to enforce consistency in pointer char (`*`) spacing.
