Search by id results (rebased onto develop)


This is the same as gh-2881 but rebased onto develop.

----

Two fixes to the results returned by ID search. To test, search for all different object types by ID:

 - Acuquisition Date and Import Date fixed for Images and other Types. Check that acquisition date is only displayed for Images and that both dates correspond to what is shown in right panel.

 - Icons should now all be appropriate for the data types. For each data type, the icon should match results returned in the rest of the table (not by ID).
