Change what is reported in 'Latest changes I can view' and considered for mtime

[Robert Lyon]

If we
- have a collection of views
- edit the access of a views in shared by me page
- edit the access of a view from the view edit page

The last modified time of the view does not update.

Changing a view's access is a modification of the view in the sense that more/less people can see the view.

We need to update the view's mtime to the same date as the view access ctime.

Not doing so causes problems for advanced reporting where we find things via viewaccess time but display view mtime

This actually needs to be fixed for any view, regardless of whether they are in a collection.

We need to update view's mtime when updating its access, that means when:

- a new secret url is added/modified/deleted
- view is shared, stop being shared, or modified shared with different sets of groups (Share with Public, Friends, Groups, ..)

[Cecilia Vela Gurovic (ceciliavg)]

There are other places to check how we update the modified view time, this is what I found through testing:
- Adding a block to a page changes the mtime of the view table, deleting a block does not
- Adding/deleting a tag to the page changes the mtime of the view table
- Adding/deleting a comment to the page updates the mtime of the view table

Cecilia, please add the details of what we discussed and agreed on to change. Thank you. :-)

Decision on when mtime update should be visible.

Premise: Make updates visible when content changes have been made. Metadata changes, access, or editing changes are not relevant.

This means in particular: When is a page displayed again as having been updated in the 'Latest changes I can view' block and moved to the front on 'Pages and collections' when in chronological view.

The original advanced reporting issue has been considered as part of this.
