Input has a suggest framework. The framework takes a piece of feedback and passes it through a set of suggest providers which can return Link objects to display to the user. Currently, the Link object has a type_. This bug covers two changes: 1. change type_ to provider 2. add version The version can be an integer--it doesn't matter. The important part is that we know when looking at results over time which version of the provider produced those results allowing for us to hone provider heuristics.
