Add local search

[clarkwinkelmann]

There's currently a mix of server-side and client-side filtering. If we can move all filtering to server-side, we can use pagination instead of loading every single extension in the front-end. flagrow.io results are always fetched in a single request.

I don't know if I should work on the above right away or if we first release this before doing more work on the filtering feature.

I think there's an issue with the js view though

This is not related to the search feature in particular, see #74

I also copied a simple debounce implementation from underscore. I'm not sure how we are supposed to include js dependencies.

Ideally we should use the lodash method, but it's not available globally and it's not a very good idea to import lodash via an extension...

a) release often and iterate. So implement full server side filtering later on; this has to be done one way or another. b) yes not sure about dependencies either, have been thinking the same now that I have a better grasp of typescript, something for the internals channel?
