Added scheme parsing to http-address param

Browse Source 
Can now listen for HTTP clients on unix sockets (and any other Go-supported stream oriented network - see golang.org/pkg/net/#Listen).  Default behaviour is unchanged, any http-address without a scheme is given the default of tcp.

Amended the README so that the usage output is up to date.
