- Implemented KRBehavior class

- Imported animations now have the auto_play and loop flags set to false by default
- Implemented Pre-Rotation, Post-Rotation, Scale Offset, Rotate Offset, Scale Pivot, and Rotate Pivot transform attributes.
- Reduced use of euler angles, replacing them with Quaternions where possible
- Fixed bug with incorrect Y rotation in KRMat4::rotate
- Material / GL Context changes have been optimized to reduce redundant glUniform calls
- New KRMesh format implemented, with support for importing BindPose matrices
- Fixed bug that caused a duplicate "default_camera" node to be added rather than picking up an existing "default_camera" node imported from FBX.  This enables animations to drive the camera correctly.
- Implemented KRVector3::Scale
- Implemented KRVector3::KRVector3(double *v);
