Add WMS map layer type

[GoogleCodeExporter]

We would like the ability to define a URL of a WMS server and show that layer 
on maps.

Design:

Use the existing 'edit map layer' interface and add another radio button with 
the option to specify a URL.

We want to be able to display our new layer on the following maps:

1. add record map.
2. my sightings map.
3. advanced review map.
4. location review map.

The layer can be added to the add record map via the existing survey map 
editing page.

Add an item to 'admin -> manage maps' where we can edit the available layers 
for the review pages. All review pages will have the same layer settings. This 
should be fairly easy to extend later if required.

Use the existing AssignedGeoMapLayer object. Currently it's a join table 
between GeoMap and GeoMapLayer. Change the following:

1. Remove the not null constraint for GeoMap
2. Add an enum, AssignedLayerOwner which can have the values 'map' and 'review'
3. Take the edit map interface from the survey editing section and reuse it for 
the editing of layers for the review pages, applying it to the slightly 
different data model.
