. Big and juicy application/WCM model refactoring

- WARNING: this change requires a new DB as the WCM model has changed significantly, yes I have probably broken a few WCM things :)

Previously the following statements were true:
 - Most of the model constants were defined in the ContentModel class - including web-client Application specific model items
 - WCMModel class was a mix of WCM repository and WCM application model constants
 - The applicationModel.xml definition file contained both web-client Application and WCM application model definitions
 - The wcmModel.xml definition file contained both WCM repository and WCM application model definitions

The following statements are now true:
 - All web-client application specific model constants have been moved from ContentModel to a new model constants class ApplicationModel
 - A new WCM application model has been defined with the prefix "wca" and URI: http://www.alfresco.org/model/wcmappmodel/1.0
 - All WCM application specific model constants have been renamed/moved from ContentModel/WCMModel to a new model constants class WCMAppModel
 - The mix of WCM application specific model definitions in contentModel.xml and applicationModel.xml has been moved to a new definition file wcmAppModel.xml
 - A patch is not required for standard Alfresco as only WCM definitions have actually changed

. Fix to issue created during workflow id/name refactor
. Fix to allow forms in the Available Content Forms panel to have correct sandbox/username context for action dialog
