Cask is not configured

After the latest PR #36 error at configuration of cask appears:

It looks like there is a new conflicting package:

Seems like there is now a font-sudo Cask, so this check breaks cask install:

if ‘sudo’ in result: return ‘Config’ I guess this check is there in case you changed HOMEBREW_CASK_OPTS? Maybe there’s a better way to check for that? by @ErikMinekus

This is a not so elegant solution I made. Probably breaks the purpose of the if in the first place:

 if 'sudo' in result:
     if 'font-sudo' not in result:
          return 'Config'

That is true, cask does come with brew. So if brew.py has an infrastructure check then this if is just a redundancy.

Should be fixed in v5.0.
