Add a CAP imagery feed to the AOI exploitation page.

@jackiekazil: Can you add details for how we can access CAP imagery? For performance, we should filter imagery feeds by the map bounds.

CAP imagery could be in here: http://fema-services2.esri.com/arcgis/rest/services/

Potential sample image set: http://fema-services2.esri.com/arcgis/rest/services/CAP_Sandy/MapServer/0/query?where=1%3D1&text=&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&f=pjson (More discussion on this here: https://github.com/jaycrossler/geoq-django/issues/42)

We really need an easier way to exploit imagery in GeoQ. Most of these are JPEGs that are loosely tied to a location, but usually are off by up to a km. There should be a way to grab an image and either automatically or manually move it onto a map, while indicating the correct angle.

This comes from the problem that geolocation is many times captured at the point of where a plane is, and sometimes the angle of the picture is captured, but the picture is of a place that is farther away.

@jaycrossler -- Hold on georectification for a bit. We (another fellow and I) have a playing with fixing that through a separate process.

We have successfully pulled in the CAP images via a layer.
