Title: Fixed compatibility issues with fontpatcher 

Fontpatcher was unable to patch the Consolas font. This is due to the fact
that Consolas is 'not' strictly a mono spaced font - it has some glyphs
which are 0 width. The added option '--fix-mono' fixes this issue by
setting all 0 width glyphs to a common width.

Windows does not seem to respect the font family name that fontforge uses.
Using the added option '--fix-win', the script will now set the font name to
be the family name. In this manner, Windows will group these fonts under the
same family. Windows still differentiates between different fonts of the
same name by their weights(italic, bold, etc.), so having fonts of the same
name is not a problem.
