Update formtool plugins, so overview varible is localised to the function.
Added configurable label for the overview summary and updated unit tests.
Removed default overview rendering for body.
Added cellRenderer for url.
Restructured javascript files for models. Moved delete confirmation to global so it can be re-used.
Updated linz require to be a relative path.
Added the number filter. Updated filters to only execute filter generation functions on the same filter once.
Fixed filter issue, where removing a filter that is accompanied by multiple filters on the same field, will remove all instance of that field filter.
Expand the URL match to ftps and mailto for URL cell-renderer.
