`ckan gui` or `ckan` (no args) will now start the GUI.

This can be tested with [this exe](http://ckan-travis.s3-website-us-east-1.amazonaws.com/ckan-v0.04-51-gfc8ad9c.exe).

Also, I have no idea what's happened with our CKAN.sln
policy stuff. I've managed to get it back to *not* inserting
tabs, but we might need a bot or similar to monitor this.

(I'm much more used to .vimrc and .perlcriticrc files!)

Also, @AlexanderDzhoganov, I opened up your GUI Program class,
I hope you're cool with that. ;)
