Update WikiFont-Glyphs

This updates us to the latest commit:

     https://github.com/munmay/WikiFont/commit/cf4bae3c710e11ccf17eac863fad35c6e0b635de

This also adjusts WikiFont-Glyph to be an independant
directory along with no longer adjusting the distributed
wikiglyph.css file.  These two changes will make it much
easier to update the font in the future.
