- on Ton's request use double versions of cos,sin,tan, sqrt etc.
just like Solid in MT_Scalar #if defined (__sun) || defined (__sun__) || defined (__sparc) || defined (__APPLE__)
- updated an url in the header of files
added raycast support for bullet (no triangle-mesh support, soon)
added python methods for 'getHitObject', getRayDirection, getHitPosition and getHitNormal for mouse over sensor,
which makes it easy for a shootout.blend demo :)
