fix (GainHonor) : compatibility fix for rev 56
Some minor fixes and new options for the .showarea and .hidearea commands:

 - Fixed Trinity::XP::GetGrayLevel function for level between 40 and 59.
 - Fixed Player::GetQuestDialogStatus so it no longer consider green quests as lowlevel ones.
 - The showarea/hidearea commands set entire zone as explored/unexplored (+ achievement) when no argument given.
