matplotlib Code

Fix some python2.6 -3 warnings. (mainly usage of has_key)

Enhancement to Axes.spy, and bugfixes:
figlegend was not plotting markers;
plot could not handle empty input arrays.

committed Jae-Joons facy box and textbox patch

Fixed some issues with unitized data. Some Patches were attempting to calculate some results without knowing how to convert (not attached to any Axes). A couple of Axes routines were assuming data was not unitized or not converting the data at the appropriate place.
