Added update functionality to ESHelper. This is now combined with the add method. Thus I have updated MyStoriesActivity for the updated method name. Started working on making the test methods for ESHelper more correct for testing.
Merged my changes to the publishing of stories with Alices changes. Should now contain the updated method name as well as encoding of the story.

Merge branch 'master' of https://github.com/CMPUT301F13T08/CMPUT301F13T08
