refactor template folders

Pulled out the fiori master-detail app into its own folder. "application" for a default Application.js app and "fiori_application" for the fiori master-detail app (Component.js). Can now easily add others if need be.
I started adding more tests but have had to comment out and wait as there is a bug just being worked on in generator-generator around the temp file. A fix has been merged but it hasn't made it to npmjs yet. May as well wait for that then do a npm update -g generator-generator. After which more tests ("it's") can be added to test the fiori app and xml generation in the standard app.
Some minor re-factoring as well...
