Removed calls to modify original tradeskill frame's position.

Removed calls to modify original tradeskill frame's position.
Fixed some issues with storing reagent information in the character's local store.
Fixed an issue when enabling/disabling the create* buttons when selecting a skill.
Changed the 'logging' (alpha-only) slash-command option to 'debug' and made it a toggle.
Changed some locale strings.  Changed the wording when acquiring intermediate items to specify that items are remaining instead of "X/Y", which seemed to imply that Y was the total value, when it's really what's left.
Added callbacks for spellcasting (start, stop, interrupt, and success) and made the queue update react to the spell success in order to update the queue count.  I think this will be more reliable than reacting to bag updates.
Cleaned up the formatting of some logging calls (alpha-only).
