[swfmill] 2 Bugs of swfmill-0.2.12

[Ralf Fuest]

Thanks for your patch.
swft_css.cpp isn't used in the svn version any more, so I only applied
the other half of the patch.
You should always look at the svn version before trying to fix something
yourself, so you don't fix something that was already fixed before (or
doesn't need to by fixed any more).
