Admin interface improvements

* Set custom title for admin pages
* Use reasonable field widths on editing pages
* Allow filtering and searching by useful fields
* Disable editing of recipe records
* Disable editing of layer fields set by the update script
* Show "Layers" instead of "Layer items" for layers
* Show "Layer dependencies" instead of "Layer dependencys"
* Show layer name in maintainers listing
