Bug 152828 Add the projectFolder property on module
When user doesn't set the resource folder path in designer, there should be a default working path for Birt to manage the report design and find the related resources. A new property should be added on Module: name: projectFolder type:URL This property only can be given from the open design method from session but should not be set after the module initialized. Concern about the backward compatiblity issue, a new method will be added. Open design with a config argument.

Library library = (Library) libraries.get( i );
			if ( theLocation.equalsIgnoreCase( library.getLocation( ) ) )
				return library;

		return null;
