Fixed an issue where http:// was being appended to certain inputs.

The issue started because VLC would append http:// on any unknown
protocol address. This "feature" has been removed because it caused
users a headache.  Users would try to manually enter an address for,
let's say, udp:// and VLC would then handle it has http://udp://.
