Title: Accept handling

See updated unittests for changed/added functionality.
Some stuff:
Better priorization (same q value does not mean even important)
Allows for quoted string params
Way more extended matching logics
Allowing for more params than only q & level
Improved parsing of stuff like application/vnd.foobar+xml
