IK: needed to change abs() to TNT::abs() (thanks brecht!)
Freetype: FT_ENCODING_UNICODE typecast to FT_CharMap (thanks intrr!)
header_image: missing include for liballoc stuff
Ketsji: needed to declare m_hitObject as public in KX_MouseFocusSensor.h.
This is probably the wrong thing to do, but KX_MouseFocusSensor.cpp
compilation fails on line 279 otherwise.
