since the css domain selectors do not work in webkit, another approach needs to
be taken to support custom css for specific sites. In config.h there is now a
list of regexes and corresponding css filenames. When a page is loaded and
userstyles are active, the first entry that matches the uri is used as
user-stylesheet-uri. The old static stylesheet is removed but can still be used
by installing a default rule matching any site at the end of the list.

Heyho,
is this useful enough to merge it upstream? Otherwise I shall put it on the
wiki.
