Support newer HTTP versions in IceCast2 codebase 

* Some servers pretending to be IceCast 2 might return newer
  version than 1.0. The example server that happens to do
  that is Cast ( https://github.com/innovate-technologies/Cast ).
* Replacing HTTP/1.0 with HTTP/1.[0-9] regex makes sure that
  we handle newer versions properly instead of showing:
  "Icecast2 - Unexpected response from server".
