Showing and ordering tags on the index page
Merge pull request #18 from wdesmonde/master

added priority field

We know this does not deploy well to Heroku - works locally but does nothing (good or bad) on Heroku. We suspect validations for Priority are being handed differently. I will update to this and see if it works locally for me.
just commemted out some of the validations in the stories model for priority to see if we can get heroku to not fuss
Heroku wnted the Gemfile.lock
ordered stories by priority and descending created_at. To be solved later is sorting by priority is alpha, not what we want.
Took first steps toward removing hard-coded text for enumeratable values (priority and status) from the story model by created two new db tables, populating them in the migrations, replicating text information as _id indexes into these tables, and changing the priority code (in MVC) to use the index. Some testing. Next step is to deploy to someone elses local machine and then continue by fixing status as we did priority.
fix bug in implementation of having separate table for priority names where edit multiple did not change priority.  fixed bug where when selecting stories with a tag, the stories were not appearing in priority order from high to low.  version 7.12
