Merge pull request #5 from rackerlabs/horizon_changes

Updated UI template files
Added basic plan creation capability.  This matches what is on the GUI.
Use solum_create_plan(), which returns the plan text as the return value,
to generate the plan according to what is on the screen to integrate
into the demo workflow.
Adding a hard coded plan file for ghost to get the demo moving.
Will re-enable the forward-looking plan generation soon.
Now appdefine can kick out a ghost app
Removed the JS access of a given button name.  Will change HTML to
call the appropriate create plan function instead.
Update to AppDeploy and Added AppManage template

- Created a new AppManage page (Manage app, auto scale, Select
environment, etc)
- Updated AppDeploy to just show workflow status.
