change ng-class to just another class and add sass partials for user pro...

...jects 

I created a new partial folder called "users" with a "_my_projects.scss" file in it. 

Some questions: 
1. is "active"/"inactive" too general of a class name for such a specific style?
2. did i organize the sass correctly?
3. is it okay to user a ternary operator to set a class? I checked ng-class and that didn't seem appropriate for what we are doing here.
