Minor change to -f handling 

Remove the ability of the -f switch to accept a comma-separated list of fonts. The user is expected
to use multiple times -f whenever he wants to specify one or more fonts. This has the side effect of
enabling the user to use fonts whose name contains a comma.

=item B<-f> I<font>
Comma separated list of fonts, lemonbar supports a maximum of five fonts (the limit can be tweaked by changing the MAX_FONT_COUNT parameter in the source).
Define the font to load into one of the five slots (the number of slots is hardcoded and can be tweaked by
changing the MAX_FONT_COUNT parameter in the source code).
