Step 1 Cause

Changed the cause logic.

The cause page now has "ADD" and "CANCEL". CANCEL brings you back to the
question you hit YES on. ADD adds the text in the field and brings you
to the Step1Cause2 page.

This displays all causes entered so far. There are DONE and ADD ANOTHER
ENTRY buttons. DONE sends you to the next question in Step 1 Activity.
ADD ANOTHER ENTRY brings you to the AddAnother activity.

This page is the same look as the cause page. The ADD button adds the
cause and brings you back to Step1Cause2 page. CANCEL brings you back to
Step1Cause2 without adding anything.
