Allowing the 'install font' to take a zip file (Bug #1312672)

When installing a normal font you have to select 4 or 5 different
files to be allowed to install the font - and most often you get these
files from 'fontSquirrel generator' in a zip file.

I've altered it so that you can either upload each file individually
or you can upload a zip file.
