* 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
