Test Case URLs

[glpoulter]

Ensure Test Cases URL are persistent, so:

• If we move the Test Cases content to the catalogue, setup appropriate aliasing or otherwise such that the original links to the Test Cases take you to the Test Case on the catalogue, not the website.
• If we leave the Test Cases content on the website and just have metadata on the catalogue then no action required though this will only be a temporary arrangement (long term we don't want to be adding things in different places)
• If the content can be moved/published elsewhere then will need to think about how best to persist the current Test Cases URL - should that url take you to the content wherever it is now published or to the catalogue?

This should be ok for first release as I've made the catalogue urls match the drupal site see #76

This should be looked at again though when the catalogue is fully released in all its glory!

This is related to release 2 and solver urls really : #102

Test Case urls are now /catalogue/test_cases/ etc as agreed in #102 This means aliases are required to be setup so that the original urls for test cases (as have been included in publications) still resolve
