. Fixes to the various servlets to allow any number of elements in the web-app context path

- currently anything other than exactly 1 element (e.g. /alfresco) will fail
  - now correctly supports any length including the root context of "/"
. Clipboard copy/move op correctly uses FileFolderService for folders (which means "Copy of…" gets prepended correctly)
. Added more explicit IDs for JbossPortal pages
