[FIX] website_mail: special case for css splitting

The css of a mail is inlined as best as possible for the mail sending.

Previously, if there was a selector like .ch[onclick="ga(this,event)"]
the simple splitting would split in the middle and get one erroneous
selector (which then would trigger an error).

With his commit, rules containing " or ' are ignored.
