Sorry for the wrong repo last time! A few bug fixes!

The same bug fixes are in this merge as before, as well as a few additional things, all changes include:

No longer crash due to iterator invalidation in MapRenderer::executeOnLoadEvents,
No longer crash due to deleting null ItemManager,
Your inventory will no longer open when you click on an NPC if you are out of range,
You can no longer "drag" items across maps,
Added an inifile option for detailed action bar tooltips (they display power description, same as in the power panel.)
