* work against more correctly assigning instance mode to entities and loot
- added manually collected data for difficulty versions of gameobjects, just boss chests for now.
update setup/source to default object source to base difficulty version if able
- update spelldifficulty table to contain the (likely) mapmode it will be used in
* refactored class loot
- implement loot mode indicators on listview for creature and gameobject loot
- show 'drops' listview tab on instance zone page
- fixes against tribute chest systems (toc / ulduar)
- fix icc gunship battle chest ownership
* don't run querys if not strictly required (e.g. query for chars from ajax context)
* prepare user globals and favorites so errors can be handled and don't destroy the template
this also allows for profiling of the affected queries
* add keys to items table to speed up querying for recipes in general and user completions in particular
* move sql files into its own folder.
* move outdated updates out of the update folder, sorted by github tags
* split up the db dump so my editor doesn't try to hang itself if i dare to touch that file
