Notes to self

Here's a sorry-for-previous-release-not-working-release; It's Fabric 0.0.2.

Hopefully it won't crash and burn as much...

Here's what's new:

• lots of minor tweaks to the innards to make it a little less hacky (still plenty to do in that regard).
  
• added a new download() operation; like put, but the other way around.
  
• local() and local_per_host() operations now halt fabric if whatever they happen to be executing terminates with an exit_code != 0.
  
• load() shoul now print a nicer message if no fabfile is found.
  

Appart from that, I've done work on a new and improved (!) shell command, but it's not ready for this version (maybe next). Also worked a little on unittesting this baby, but I haven't got much to show for that, either.
