Default LDoN Open Button Support
Background:
With LDoN a special type of treasure chest was introduced, which players could "open" by clicking on the Open pushbutton. Most everyone should be familiar with this type of object.

Technically, chests are nothing other than a special type of NPC, having a spawnpoint and loot like any other mob. Opening a chest is instantly killing this mob, causing it to play its death animation (ie chest cracking open).

I've gone ahead and implemented an initial version of this functionality. It's still vs 1030, but it should be no problem to apply to a later version, since it's mostly one line additions. Since I only have a Titanium client to test with, I've only updated the Titanium Client opcode list so this will NOT work out of the box for any other clients.

People with access to other clients should try and see if they can find the "Open" Opcode for their client and update the config files accordingly.

The follow patch looks huge; all it really does is prevent players from getting
EXP for their chest "kills". I did some code reformatting, that is why there's so many changes.

To test it, create a mob with any race/level, class=62 (LDON Chest) and bodytype=33 (BT_Boxes). I've included the bodytype criteria in order to make sure that there's very little chance of there being actual mobs with both class=62 and bodytype=33 in your databases.

Enjoy,
-Chris
