Addition of sorting to API results

[ivanstegic]

Do a search for "gun control" on the API:

https://api.whitehouse.gov/v1/petitions.jsonp?title=gun%20control

Results are returns in date created order. Please consider adding other sorting options? It would be AWESOME to see the results sorted by:

• signatureCount
• title

It would probably be incredible to see the data sorted by other parameters, but the most interesting to me is by signatureCount, which really would indicate popularity to me.

Interesting ideas - the team's culling through issues and feedback from the hackathon, we'll see about getting this into the queue.

Thanks, Peter -- it would really assist in finding popular petitions in the instant search especially.
