Support --help for helpful help

[mistresseve666]

If you try to pass --help to any of the sub commands, you just get a lovely error message:

Error: Cluster --help does not exist in decking.json
    at Decking._run (/usr/local/lib/node_modules/decking/lib/decking.js:231:11)
    at Decking.commands.status (/usr/local/lib/node_modules/decking/lib/decking.js:108:17)
    at Decking.execute (/usr/local/lib/node_modules/decking/lib/decking.js:57:13)
    at Object._onImmediate (/usr/local/lib/node_modules/decking/bin/decking:25:20)
    at processImmediate [as _immediateCallback] (timers.js:330:15)

Would be nice to actually produce help output. Maybe even also ignore anything that starts with a - or -- from being a cluster name?

Seems kind of evil to name your cluster --help.

Cheers for all these. Will start taking a look when I get back next week.
