RAXAJSS-329 - Automated Prettify of all JavaScript files

Wrote ```prettyjs.py``` to auto-beautify all .js files in Raxa-JSS source tree. It is currently in the base directory, where it should run from (```/Raxa-JSS```) but we ought to move such tools elsewhere (perhaps another github repo for "raxa-tools").
* To ignore a file or path, it must be added to the blacklist. 
* Must be run from the ```/Raxa-JSS``` directory
* Requires user confirmation before each beautification, to avoid accidentally affecting files (can use ```--no-confirm``` option, too)
* Creates .pbak files to backup any file affected by beautification. To ignore these when doing a commit, use ```git add -u```  , "update", to add only already tracked files to the changelist

Beautified all current .js files in the source tree.
