added menu items to "Download Manifest"
added CSV downloaded manifest at "services/api/edit/manifest-csv/{pid}"
manifest generated from Solr, but data is marshalled locally in a big hashmap

needs to be prevented from running on Collections object
controller also includes a JSON endpoint of the same data (not downloaded) at "services/api/edit/manifest/{pid}"
renames manifest controller
adds a fileinfo controller for downloading a list of files with checksums, length and other info
add menu item for file info downloading
revised to spit data directly to CSV, instead of marshaling it in memory
only presents manifest download menu items on containers
adds a Copy PID to Clipboard menu item
removed CTRL-C verbage
consistent copy pid labels
escaped quotes in CSV are two double quotes
