Thought they did change the URL of their load balancers,
guess I was wrong.

Closes #2

Also various fixes.
Also some debug stuff, make sure to remove that later.

Rules can now come in 3 different formats:
- AdBlock rules
- Host lists
- Domains lists
All will be converted into domain lists and aggregated
(only AdBlock rules matching a whole domain will be kept).

Subdomains will now be matched if it is a subdomain of any domain of the
rule.
It is way faster (seconds rather than hours!) but less flexible
(although it shouldn't be a problem).
