Site Search Tool - Phase 3

This carries things all the way up to doing a rough, unprocessed Quality Rated query.

Several date range calculation methods are now in app_controller.

Query Conditions construction tools are are in Content Controller. These take the data from the POSTed search form and run them through logic to construct to proper conditions array.

At the end, a simple verification query is run.
Site Search Tool - Phase 3.5

The search now is more refined, pulling the data then organizing it into categories while counting how many Content/Image pairs are in each Content.slug group.

The Search View prints link blocks appropriate to each category though these need some refinement.
Site Search Tool - Phase 3.75

This carries the site search tools into the specialized Image Edit side of the world.

Now the three image editing pages, image_grid, multi_add, and clean_up, can use the site search tool to get record sets.

There may be problems that come up. There is a lot of junk code left over from my previous admin-only edit tool on the image-edit side. That stuff is still partially functional because it provides default found sets if no search was done.

Other changes to refine the code were made here and there too.

Do app_controller which has all the new search methods

Start on app_helper, specifically the teaser blocks and search blocks
cobble together fixes for multi_add

multi-add is pretty broken after installation of the search tool. These are hacks to make it operational. This needs serious work later.
