Remove all console logs

[djrobotfreak]

Time to remove all the default javascript console logs, and switch to using angular $log. This will give us more control over what is shown when, because we can set the level to display (error only, error + log, error+log+debug, etc..) and it's alot cleaner.

This is kind of a major operation, because we have to go into every controller with a console log and add the dependency $log. Then we can find and replace all the console logs.
