Shrines now periodically validate their lighting state.

Should fix #61. Every 10 seconds the alcove's lighting state will be checked to see if it's stuck.
Verbosity reduction
Support for updating character gear with full reload, add warning for missing slot or dds file.

Working on #55. Right now this creates duplicates of items, still needs work.
Gracefully handle deletion of Shrine data file. Fixes #63, too.

Shrine save hangs were caused by saved player data resulting in SaveCurrentPlayer returning False instead of firing events. Fixed it by always forcing a full save when using the book.
Shrine trophies now respond properly to lighting priority requests.
Removed now-useless code.
Characters now sent to staging cell when alcove is deactivated.
