Paginate, filter, and sort the import list

We have hundreds of videos in our Backlot, bur since the API limit for queries is 500, we only receive a partial list when attempting to run an import. It'd be great if we could 1) paginate the total list, 2) allow sorting by oldest or created ascending/descending instead of just newest, and 3) filter the list to only include videos that have not yet been imported.

Ideally, the filtering feature would be done in a way that we can switch between filtered and not. Perhaps we should store all of this information in a table, so that we can integrate with Views? This would cut down on costly (and sometimes long) calls to the API. We might be able to ping Backlot to see if there are any new items, but I can't seem any direct API calls to do that, so it might be more involved. Additionally, we could compare the $last_sync variable to see if we've surpassed a set schedule. Finally, having Views integration would allow us automatic filtration or configuring pages in other ways, such as with tabs.

Sorting and filtering the list does require new options to be added to the various API calls that are initiated, since the V2 Ooyala API does allow for more advanced queries. (See http://support.ooyala.com/developers/documentation/api/asset_video.html)

Since these are all semi-immediate needs for us, I'll try to come up with some solutions and see if they work for others. Thoughts, patches and further discussion are welcome.
