James D. Callahan III:
    - In TRAINER_SHOW: Added storing of whether or not requirements are met...and did so long enough ago that I no longer remember why.
    - Replaced skill_ranks with MY_PROFESSIONS.
    - Replaced TRADE_SKILL_CLOSE with TRADE_SKILL_SHOW.
    - Added preliminary LDB support. Put in check to not save automatic skills (armor types per class, for example). Check for tradeskill trainer - if not for a tradeskill the toon knows, don't save info.
    - Revamped initial database and added saving of category/skill information - may change format in the future.
    - Fixed the preservation of trainer filter preferences, and changed the trainer information to not use a single table - it was duplicating data for all trainers.
    - Removed TRAINER_CLOSED() - all trainer-related code is now in TRAINER_SHOW(). Added check in TRADE_SKILL_CLOSE() so we aren't saving linked trade skill information as though it were our own.
    - Basic skeletal code structure.
