Modified OptionFrame layout and added GroupRoll Manager Frame.

Minor tweaks to LazyPigMultibox.lua.
Moved/Added debug/print functions to the head of the file.
Changed GROUPMINI (now called POP_LOOTGROUP) usage/name. Now LootMethod can be changed from the OptionFrame.
It can be set to FreeForAll or GroupLoot. Choosing GroupLoot change the threshold to "poor", so even gray items can be rolled/distribuited.
POPFFA is now called POP_LOOTFFA.
Added LOOTMETHOD and LOOTTHRESHOLD settings.
Function SetFFA renamed to LootMethodTick.
Function SetLootMethod added.
The CommunicationProtocol has two new commands. "lpm_invslot_request" and "lpm_invslot_reply". These will deal with CompareTooltips in the LootFrame.
