Quick fix for ImageControl default regions.
Added public methods on ScriptController for registering and unregistering global script callback functions (i.e. initiailze, finalize, update, render, touchEvent, keyEvent, etc). Multiple registered functions per callback are now supported and scripts can register themselves.

Fixed lua dofile on Windows
Fixed #909
