Reorganized directories

Created new directories with more descriptive names that specify how
the files should be used and separated the files into their respective
directories.
Added web fonts

Downloaded the web fonts from the Crimson Webfonts v2013.12 release and
added them to the new Web Fonts directory.
Regenerated web font files

Using the generator at Font Squirrel, generated new web font files
based off the OTF files, with the WebOnly protection setting checked,
in order to prevent optimized web TTF files from being installed as
desktop fonts.
