* minor rework
* fixed columns of tab item loot
* fixed lookup of classes/races (as they are the only type used as bitmask)
* implemented reverse lookups everywhere (arguably class, race and skill are too spammy)
* reverse lookups no longer contain redundant data
* changed how the groupKey is set, so there are no more cases that can't be looked up
* fixes#273
* title: added tab 'criteria-of'
* prevent direct access to some internal files where applicable and reword error for others
* if CFG_DEBUG is set also enable debug in client javascript
* non-breaking formatting changes
* define regions and missing locales for later use
* Conditions: loot rows initially have no 'id'
* fixed building talent string for hunter pets (different talents can occupy the same row/col spot)
* added keys loot cols on creature table
* fixed trying to show itemset type for itemsets without type
* fixed waypoint calculation when moving entity between floors
* rewritten and moved to its own class, should be easier to expand in the future
* add missing sources and types from TrinityCore
* implement conditions on Areatrigger and Loot containers
* implement reverse lookups (e.g. a spell is a conditional for something else)
* general beautification pass .. should be more legible in general
NOTE:
* texts have been changed, so the existing translation for esES ist gone
* selecting and describing condition targets is still wonky
