Change the modify date on each click on the file

[meaz]

The lists of files in Nextcloud folders, has a column "Modified", which shows an incorrect value for .pads. What I mean, is that as pads are edited outside of ownpad (they are directly into the etherpad instance), if you change something on the pad, it is not reflected on the list of files in Nextcloud, so you can't know that something changed in the pad. And it's a pain to work with .pads when the number grows. In particular due to the temporary limitation of deletion set on some etherpad instance.

Something that could help would be to change the modify date on each click on the file. Like this, it would assume that the pad has been modified. In that way you could have better indication on when was the last time you used the pad.
