Add name, dir opts; escape quoted args

[emanuelfeld]

Adds name (-n, —name) and dir (-d, —dir) opts for init script.

Escapes quotes on args to preserve arg values with spaces.

Don’t think the eval in orgwide is objectionable in this case. Perhaps there’s a better way of preserving spaces, though..

Nice additions!

(I may change --dir to --dest in the future)

[emanuelfeld]

Yeah, --dest is likely a better convention.
