Ignore q-values when matching Accept-Encoding

[Hexay]

Accept-Encoding: gzip;q=1.0 didn't match gzip

I agree that the Accept-Encoding header is not handled 100% correct currently, it doesn't support the ;q=x quality appendix and also doesn't support * .. however i am not sure if the HttpHeader class like this is the correct way to handle this, i'll take a look on how this should be fixed in a bit 👍

I implemented it slightly differently, but i am not fully happy still. I guess at some point i will need to revisit how headers are parsed entirely :D

Edit: The reason i didn't want to have it in HttpHeader is because the quality-parameter syntax is technically not universally valid for every type of header, so parsing it there seemed not clean to me..
