[qutebrowser] Extend ad blocking to allow single URL blocking.

[Viacheslav Chimishuk]

I can see ublock uses regexp for its list. Implementing regexp support
we can reuse their files, which will get us a huge
benefit. Unfortunately their format is not compatible with UrlPattern
we use and looks much more complicated than a simple regexp. IMHO, it
is better to start with simple substring match for now.
