Year selection implementation

[contolini]

@sleitner Here's a prototype of how the year selection will work. It's incredibly hacky at the moment but it demonstrates how we can handle the search endpoints.

On the institutions search page, instead of the typeahead requesting:

http://localhost:8081/institutions/search/?auto=1&q=wells

It now requests:

http://localhost:8081/institutions/search/?auto=1&year=2014&q=wells

Or 2013 if you selected that in the dropdown at http://localhost:8081/institutions/. We can discuss on Monday.

New and improved version incoming.
