Collection view

[dannylamb]

JIRA Ticket: Islandora/documentation#1336

What does this Pull Request do?

Adds a collection view, a simple controller to let folks select what content type to create a new collection, and some tests around that controller (and two others).

How should this be tested?

• Pull in this pr
• re-import islandora_core_feature to get the view
• go to admin/content
• you should see a tab for 'Collections', click on it
  
• you should see Collections on your site, their # of children, and disk usage
  
• click 'Add Collection'
• You should be presented with a list of content types a la /node/{nid}/members/add
  
• Click on 'Repository Item'
• You should get redirected to the creation form for a collection, with the model field prepopulated to have the 'Collection' term.
  

Additional Notes:

Is this sort of thing remotely useful?

Kicking off tests for this one now that #749 has landed. Would be good to get some feedback on this one. I think it's a nice addition to the interface.

I don't see the "Add Collection" button on the Collections tab, but up until then this was working as described.

is this being worked on, or won't be used?, or maybe once we get to a wizard to create content off the only content type we have now this won't be needed?
