Fix the naming conventions.
Master should be reserved to identify a bots Master.
groupleaders are not necessarily group masters and it should be clear
what the bot is looking for. (In most solo cases leader=master)
PlayerbotAI::FindOilFor was making the server randomly crashing
ChooseTravelTargetAction::getNewTarget: when active bot groupping was making the server crash as looking for unexisting params
Several bug fixes and tweak to Quest and Group
New fucntionnality:
Bots will now share quests randomly to their party
Bots will try to accomplish group member quest before moving on to new target
Bots will try to sells items only after few levels ( 5 ) when in group
When dropping a quest bots will try to select a new one they are on instead of idling for few time
Bots will no longuer try to invite themselfs to group or if group is full
Bots are now allowed to leave party by themself
Bots in groupe if not leader are forbbiden to tag in bgs
Bots in bot-groups no have a more limited range to look for grind target
