Axis constraint in transform for grab mode
Axis constraint in size mode

note: the original behavior when constraining with middle mouse in object mode is weird. I've leave it that way, but I think it would be a good time to fix it. Another thing: in object mode, you can only constrain size to local axis. Global axis would involve either screwing the matrix (which stinks) or modifying the vert coords directly (which is a no no)

Please also note that this breaks the mirroring combo.
I'll be commiting my edit mode mirror function soon to fix that.

Coder note:

You can now call the transform function with an additional parameter to constraint to an axis.
example:

transform('g'*'X')
transform('s'*'y')
transform('r'*'z')

Capital axis letter for global axis, lower case for local axis
