Client Map Layer URL parser

The Map Layer URL parser allow the user to show specified layers when the client start, overriding the default settings for the toc.

The user can use the ShowMapLayers or HideMapLayers keys in the URL to either show a set of layers or to hide them. The value should the layer id and map engine id separated by '/', i.e. roads/me.vector. Optionally, the toc layer id (id attribute from the toc for the specified layer) could be specified without the need to specify layer id or Map Engine. Multiple layers should be comma separated.

Example:

Show/Hide layers by (layer id)/mapengine and by toc layer id.
