Added client and server side support for transient properties

- As long as a template for a control is configured fields without a definition can now be displayed
 - Added 3 well known transient properties; mimetype, encoding and size (these are similar to the propertyResolvers we had in the JSF client)
 - Added explicit persistence handling for the new transient properties, the name property and adds aspect if title/description and/or author property is present
 - Added saveForm test
