It makes the contents of _heroku completion file for zsh

It mostly works now, but it's still a work in progress

Do you use oh-my-zsh? When this completion is finished, I'll try and get this as a proper plugin in there. In the meantime make a plugins/heroku directory in custom.

Add heroku to your plugins list in .zshrc, and do this

ruby completion_generator.rb > ~/.oh-my-zsh/custom/plugins/heroku/_heroku

You'll also need a version of oh-my-zsh with this pull request merged in, or make this change to your oh-my-zsh.sh file yourself

If you don't use oh-my-zsh, then add this in a directory that gets autoloaded somewhere

• heroku gem >= v2.0
• zsh 4.3.11 - it sorta works with earlier versions, but you cant complete after the : in some of the commands
