MapTool 1.1 Development Release Build 3

[trevor]

This release is specifically targeted to fixing the lag issue.

- Graphic performance improvements

Ok, I've combed through the code looking for dangling graphics objects.

I found one in the drawable rendering code. The only problem is that code hasn't changed in a loooong time, and the lag issue seems more recent. Needed to be fixed anyway.

Also I found a spot that caused a huge amount of image recreation when dragging tokens, which I fixed. This might account for the slowness in dragging.

I don't know if these two will fix the slow rendering issue, but they are a step in the right direction.

I need everybody to hammer on this version and see if you still get the over-time slowdown.
