Changes to GoHome inspired by ethulhu/dwm in #doc, eve of 2013-01-21.

Conversation follows:

> < DoCitten> Ladies and Gentlemen, your attention please: DoC Labs will be closing in 20 minutes
>  \* ethulhu is neither lady nor gentleman, does not give DoCitten attention
> < DoCitten> Ladies and Gentlemen, your attention please: DoC Labs will be closing in 10 minutes
> < DoCitten> A dry, twitty comment should go here!
> < DoCitten> Ladies and Gentlemen, your attention please: DoC Labs will be closing in 5 minutes
> < DoCitten> Please save, commit and push your work, log off, and try not to get locked in!
> <@dwm> Hmm.  *ponders alternative wording*
> <@dwm> Yeah, s/Ladies and Gentlemen, your attention please/Notice/
> <@dwm> Or just 'Note:'
> < ethulhu> or just "Your attention please: DoC labs will be closing in T minus 10 minutes"
> <@dwm> Indeed.
> < ethulhu> or "oi, you lot, GO HOME AND SLEEP AND STUFF!"
> <@dwm> Yes, that flows more nicely.
> < ethulhu> :)
> <@dwm> ROFL
