switch to subversion tomorrow Tuesday 28 Feb

Hi all,

I will endeavor to switch matplotlib to a subversion repository (newly
available courtesy of SourceForge) tomorrow afternoon/evening
(US/Pacific time) unless I hear pleas from developers with unmerged changes.

I believe the new command for anonymous checkout of matplotlib will be:
svn co https://svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib

I'll post the developer checkout command on the matplotlib-devel list
when I figure it out.
