The aim is to enhance the `/sage/matrix/matrix2.pyx` file with cython's
properties to call `self.transpose()` and other methods more quickly. A
shortcut like` self.T` is resolved to `self.transpose()`. Shortcuts should
be similar to other environments like `numpy`. Shortcuts added are:
* m.T -> m.transpose()
* m.I -> m.inverse()
* m.C -> m.conjugate()
* m.H -> m.conjugate().transpose()

Comment(by leif):
Attached rebased versions of two patches because of fuzz 2.
