Merge branch 'current-sprint' into notebook-ui
Wrap text area in div with class set to col-sm-3. The col-sm-3 class was
being set on the text area itself. This wasn't affecting its
size. Moving it to a bounding div fixed the issue.
ISSUE#604. "Process -" was being appended each time to the list of
processes a user could choose. If the user then started a second process
they would have the categories as "Process - Process -".

The code was updated to check for the existence of "Process -". This
indicates that the templates have already been processed and don't need
to be processed again.
Remove console statements.
ISSUE#605. Even though we were setting the step, the step details were
not showing up on the webpage. It appears that the controller for the
directive for step display wasn't instantiated when the event to show a
step was fired. That or it wasn't dirty checking at that point. I fixed
this by wrapping setting the step in a $timeout.
