Fix: Don't crash on kick without user

[TheBenji]

If you do "/KICK " and don't specify a user the server crashes

home/ben/workspace/ircd.js/lib/commands.js:123 userNames = users.split(','), ^ TypeError: Cannot call method 'split' of undefined at Object.Commands.KICK (/home/ben/workspace/ircd.js/lib/commands.js:123:27) at Object.Server.respondToMessage (/home/ben/workspace/ircd.js/lib/server.js:171:36) at Object.Server.respond (/home/ben/workspace/ircd.js/lib/server.js:181:14) at Object.Server.data (/home/ben/workspace/ircd.js/lib/server.js:320:10) at Carrier. (/home/ben/workspace/ircd.js/lib/server.js:277:51) at Carrier.emit (events.js:95:17) at /home/ben/workspace/ircd.js/node_modules/carrier/lib/carrier.js:71:15 at process._tickCallback (node.js:419:13)

Doesn't happen anymore with this fix and just sends an "needs more arguments"

Good catch, thanks for the fix. Your patch seems to alter the indentation of several lines. Could you please clean that up?

[TheBenji]

Just seems like it. The whole part between l137-160 is now within the "else"-block and therefore the indentation moved a little.

I (well, my editor :P) also removed the trailing whitespaces (l336 & l498).

Hope that makes sense
