Initial TeamFrame Support. DON'T USE THIS!

Added SavedVariables for UI options.
Initial import for LPM_TeamFrame.lua. Still in development.
UI options are now saved in the new LPMULTIBOX_UI table. Still missing "SavePosition" support.
Name Consolidation.

Quite a few "Option" were changed to "Options"
Every Options window will now close upon ESC press.
TeamPartyFrames initial implementation.

Most (all?) functions related to the UI are not prefixed with "LPM_" instead of "LazyPigMultibox_".
LPM_Utils contains now new functions for "SendAddonMessage", with a proper implementation (hopefully).
Exchaning messages should now display proper debugging info on both Master and Slaves.
