BGE: fix more matrix transpose bugs in assignement to game object matrices.

Assignment to KX_GameObject localOrientation and
worldOrientation matrices was assuming row-major matrix
although reading these matrices was returning a column-major
MathUtils object.

The faulty function (PyMatTo) is fixed and all matrices
in python are now assumed column-major.

This function is also used in the following methods:

BL_Shader.setUniformMatrix4()
BL_Shader.setUniformMatrix3()

(No change in scripts if you didn't specify the optional
transpose parameter: the default value is changed so
that column-major matrices are assumed as before.)

KX_Camera.projection_matrix

(assignement to this attribute now requires a column-major
matrix and you must fix your script if you were setting
a value to this attribute.)
