L00per

Fix an endless loop in the IRC message parser, should fix issue #4.

The parser skips empty lines, but didn't properly adjust the looping index. That should be fixed now.

P.S.: Now building on more Travis platforms (e.g. Linux Swift 4.2, and XcodeX)

Extra Protocol

Decouple the protocol implementation from the client to make it useful to arbitrary higher level frameworks. The client now lives in an extra package over at Noze.io.
