Metacat

make RestServlet and ResourceHandler extendible for D1 CN and MN handlers

use session member variable now that we actually have it

isAuthorized: check for nulls in Session subjects, catch any unexpected errors and deny access when in doubt

remove CrudService calls in favor of MNodeService

include commons-configuration jar -- runtime dep for d1_common

Remove setParamsFromRequest() from D1NodeService. This was called (previously as CrudService) from ResourceHandler, but will be deprecated in favor of manually creating a param map for each method that needs to pass params on to MetacatHandler.

Implement [MN|CN]Storage.create() in D1NodeService. Since MetacatHandler requires an IP for event logging, we pass in the metacat URL (hold over from CrudService). To do this in the abstract D1NodeService, change the constructors to take metacatUrl as a parameter and get the URL from the metacat properties file in getInstance() of the subclasses. Needs testing.

Add a dataone.serviceName property (set to 'd1') to remove hardcoded 'd1' strings in the codebase.

include URL in resolve() method as well as placeholder for preference
