Use webjars to retrieve moment.js

Conflicts:

After recreating the pom, added back in the webjar dependancy for moment.
Modified how the displayToPublicDate is handled. Format so time zone is not shown and send the displayed time back to the server.
Put module constants for Person and Contributor in a .value service.
Removed unused variables
Added angular, bootstrap and jquery to libraries fetched using webjars. We should consider doing the rest of the ones we can in the future.
For temporal start and temporal end, added formating to show only date portion of time.
