Web-UI / Add a graph to the Storage overview page with new revisions count

Hello,

the Storage page of Web-UI currently offers Size, Revisions and Chunks graphs with data for each day / backup when storages were checked.

I think it would be beneficial to have 4th graph with new revisions count per day (same granularity as other graphs) for each backup. As with the other data, it would be only available after the storage is checked.

Reason: this new graph would allow us to see when some backups are not running as usual (drop in new revisions or no new revisions at all) simply by checking the storages.

Thank you
Robert
