[Launcher] add a start lan under the singleplayer button in the launcher

[n00b7]

for people who have friends who want to play classicube at the same house this would be useful

once you click the button a tab would appear saying:

lan game set on ip: (random ip) click ok to start

[ok]

then the server could be opened by using the direct connect button type/paste the ip into the box and click ok

and you will join the lan

(it would be a neat way to have a private server)

It's possible to connect to local servers using the following syntax:

mc://123.45.67.89/username (Implies using port 25565)

Or

mc://123.45.67.89:12345/username (For non-standard ports)
