Add a 'Manage Collections' page

[dannylamb]

Use views to make a 'manage collections' page that shows useful info about your collections and gives you a shortcut action link to make a new collection.

PR up for a first pass at this

We took a similar, yet slightly different approach to this where we define a new drupal content type and set up the contexts and define some (fewer) fields. We could make a feature branch so that it can be tested out as well. One benefit is that the "Collection content type" approach is controllable for access to different roles through drupal core permissions already. There are other pros & cons to each approach... I'd like to demo ours and discuss?

As for a separate page for create and managing collections, the "Add Content" would have it listed for those with permission to add. Some views and blocks could easily be made to provide various levels of management.
