Matrix4f eq doesn't work (but the others do...)

[Jeff Packer]

EDIT: I don't think richcompare is set properly.

Matrix4f __eq__ doesn't work when the objects are different but it works when they are the same. Other types of matrices don't have this problem.

eg:

>>> from pyeigen import *
>>> n = Matrix4f(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)
>>> m = Matrix4f(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)
>>> m == n # Should be True!
False #crud, got False
>>> n == n # This works!
True
>>> m < n # Should raise
False
>>> m = Matrix3f(1,2,3,4,5,6,7,8,9,)
>>> n = Matrix3f(1,2,3,4,5,6,7,8,9,)
>>> n == m # This works!
True
>>> n = Matrix2f(1,2,3,4,)
>>> m = Matrix2f(1,2,3,4,)
>>> n == m # This works!
True
>>> m < n
