matplotlib Code

Fix a number of font manager issues:
1) AFM fonts now store stretch information in the FontManager database
2) pdf.use14corefonts and ps.useafm will now only use the afm files for their respective formats
3) The fontList.cache file is now versioned -- if the version doesn't match the current version of matplotlib it is thrown away and regenerated

Fix previous EINTR fix in case fc-list cannot be run
