Upgrade quassel to version 0.8.0.
Adjust the patch to apply to the altered files.
Add another line to the patch to support `<QtWebKit/QWebSettings>`
otherwise there's a compile error.
Tested on Lion with clang and llvm from XCode-4.3.3 by starting
the chat gui.
ClosesHomebrew/homebrew#12939.

brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
