Dashboard-side changes to start AIC creation chain

refs #5803

Added a CreateAICForm and submit button to the AIP search page that is
populated with the results information.  The results information is posted
to create_aic which creates an entry in a WatchedDirectory to start a
MicroServiceChain.  The directory is populated with files corresponding to
the AIPs that should go in the AIC - the filenames are the UUID, and the
contents are the AIP name.

Also, updated urls.py files to use url() instead of just tuples and did
minor cleanup.
New show AIC checkbox and AIC identifier column in Archival Storage

refs #5898

Added 'Show AIC?' checkbox to Archival Storage search that displays a
column with the AIC identitfier (if AIC) or isPartOf field (if AIP).
Updated query parameter for file mode. Removed defunct StorageSearchForm.
