Fixed bug reversing Gustaf changes in expr

  Now including SLAs with "group membership"

  Now showing only "open" SLAs. Also, the SLA's main project
  (if any) needs to be open.

  This way, the translation strings from intranet-core will be used.

  - Moved main audit_impl into intranet-core
  - Replaced im_project_audit by im_audit

  ns_info pageroot was deprecated anyway, so it's not replaced
  with acs_root_dir

  Moving slow Sencha portlets to Tickets -> Dashboard page

fixed widget customer_contact_select_ajax - When customer_contact_id is null do not show configuration items

   When customer_contact_id is null do not show configuration items

  Moved audit out of the ticket::new creation.
  The audit inside the transaction {...} gave
  bad errors, because the object wasn't yet
  created in acs_objects.

  Removed ticket_hardware_id, because it isn't really used
