First attempt to add guake and guake.indicator.

 This only manages the packages being installed, currently.
Added ppa for guake-indicator
Fixed guake-indicator.

The dash in the name was causing issues with jina. I changed the name to just 'indicator', hoping that the variable scope won't mess with other formulas in the future.

I also fixed the if statement for if the ppa was provided or not.
Added json config
First attempt to dynamically create json config
Add base files for indicator and autostart
Added config with static keybindings file
Changed indicator state name to guake-indicator
Templatize the keybindings to pull from pillar
Templatized guake-indicator.json.jinja to pull from pillar
Fixed user list in guake.autostart
Updated readme and pillar example
Cleaned up config
Merge pull request #1 from matthew-parlette/guake-with-indicator
