ProfessionBook

- Added a Share button directly on the profession window. No more digging
  through the minimap menu just to link a recipe list. 
- The Share button gives you quick access to link in Say, Party, Guild, Raid,
  Trade, General, LookingForGroup, and Services channels.
- You can also send your profession data to another player by name
  through a "Send to player..." option that pops up a simple name prompt.
- Same new channel options (General, LFG, Services) were added to the minimap
  dropdown too, so everything stays consistent.
- Minimap button still works exactly the same as before.
