I guess implementing Chrome's URL patter syntax here can be harder to
implement. Ok, I'll try to implement it the way you proposed.

Simple domain name is not compatible with pattern syntax -- it
requires scheme and path parts. In this case we need to treat foo.com
as *://foo.com/*

I thought that adblock will be moved outside the core later, after
plugins support will be finished. Like you introduce plugin support
and after extract existing core parts (which you want to be a plugin)
one by one.
