run all project CSS through csstidy

The inconsistent code styling was making me head hurt looking for where
things were set and it was too much to review by hand. I ended up
running everything through css tidy to normalize the order of properties
and selectors, whitespace, value styles, etc. I opted not to have it
optimize for shorthand values,  merge duplicates, or any other options I
thought would make it less readable.

Since the output of csstidy is not indented, I tweaked the output to use
one selector per line and re-indented the whole thing using vim's syntax
plugin. Here is a quick vim scrip to duplicate the same results:

    :%!csstidy % --silent=true --preserve_css=true --sort_selectors=1 --merge_selectors=0 --compress_font-weight=false
    :%!sed '/{$/s/,/,\n/g'
    :%s/: */: /g
    :norm gg=G
