Matei aa50820d9a #Unit AI: Aggressive, defensive and stand ground stances.
Also split Entity.cpp further, moving the rendering code to
EntityRendering.cpp and the JS interface code to
EntityScriptInterface.cpp. This makes each individual file smaller
(about 1000 lines still!) and lets them be compiled independently.

This was SVN commit r4314.
