WIP - Better theme specs (including specs that cover views)

**WIP** - still working on feature-style specs for the authority pages

Fix the spec theme mechanisms and stop the main app specs from loading the theme customisations
Closes #89 

Fix a view bug - and test it! - that prevented the number of matching applications from showing in the search results sidebar
Closes #175 

Add some feature-style specs for the views (ongoing)
Closes #140 

( I see some commit squashing in my future )
