allow tradeskill / craft information without frame open

[Shamino]

Ability to retrieve tradeskill/profession info without having to have the frame open.

GetNumTradeSkills, GetTradeSkillInfo, GetTradeSkillNumReagents, GetTradeSkillReagentInfo and the respective Craft ones, all rely on the frame being opened to retrieve this information.

Possibly create new functions that return this information without the frame being opened.
example
GetNumTradeSkills(professionName)
GetTradeSkillInfo(profession, i);
...etc..
