[matplotlib-devel] funky strings in rec2csv

As a followup to the work on floats, I fixed rec2csv to deal with funky 
strings (strings with commas and quotes). I've checked this is as r4749, 
but I thought I'd announce here in case someone (John, in particular) 
was depending on some peculiar aspect of the old implementation. If 
there is something you depend on, can you update the unittests in 
unit/mlab_unit.py to check for the behavior you need?

Also, John, I didn't see mlab.FormatString being used anywhere, but I 
didn't want to change it, either. So I made FormatString2 and used it. 
But if there's no known use of FormatString, lets kill the original and 
more FormatString2 into its place.
