Fix FancyBboxPatch Typo

[jakevdp]

A tiny cosmetic fix. Previous behavior was

>>> from matplotlib.patches import FancyBboxPatch
>>> print FancyBboxPatch((0, 0), 1, 1)
FancyBboxPatchFancyBboxPatch(0,0;1x1)

After this PR it is

>>> print FancyBboxPatch((0, 0), 1, 1)
FancyBboxPatch(0,0;1x1)

There are two possible ways of fixing this bug: the way you did it, or by keeping the self.__class__.__name__ and deleting the "FancyBboxPatch" part of the following string. The advantage of the second way is that it gives the correct result for subclasses of FancyBboxPatch.

I think the second way of fixing this is the better choice (and the places where the class name is hard-coded in should be changed opportunistically).

[jakevdp]

OK. I noticed that both strategies are used in different classes throughout the file - I chose one of them arbitrarily.

I think this is ready

@efiring This should probably be cherry picked to 1.3.x as well.
