Added URL link pseudo files support. Split pseudo file classes to allow local filesystem and
in memory pseudo files. Drag/drop and URL link pseudo files now only appear when using CIFS. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@2229 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
