Enable gaining of group leadership while in raids

Note: raid leaders can only gain raid leadership, so they won't
ever gain group leadership while leading a raid, even if they don't
end up gaining group due to the restrictions.

From what I can tell, this should be in line with live
Updated #peekinv to display item links properly in RoF clients
Fixed server<->corpse translators to reflect what actually needs to be translated (should not have affected anything in the old configuration)
Implement group mentoring while in raids (SoF+ only)

Note: This does not allow the raid leader to share raid leader XP
and since the raid leader doesn't gain group leadership, they can't
share that either.
Implement Group Inspect Buffs for raids
Switch Inspect Buffs to use the OP code

Client 6.2 is SOL until someone find the op for that client
Missed one!
Merge branch 'master' of https://github.com/EQEmu/Server
Allow npc_types field 'special_abilities' to be set as null in database.
Changed due to issues when trying to copy npcs or remove abilities from
the field directly in the dataabase.

Fix so NPC don't ghost when casting spells from scripts while moving.
Fix for bug with Discipline recast timers preventing them from
working properly if you used a focus effect to reduce recast time
to zero.

(Specifically the recast timer failed to reset in the situation
where you had already used the disc WIHTOUT the focus applied, then applied
the focus and tried to have it reduced).
Small update to prior commit.
Bugfix: Corpse stays locked when looting fails

If looting fails either because of cooldown or there are items on your
cursor, the client is sent an end loot packet- the client releases the
corpse but no one else can loot. This simply resets BeingLootedBy in
this instance.
