[Feature] Hide empty fields in view mode

[Tekl]

I switched from Enpass to Strongbox. The importer has added many empty fields, so I've to scroll a lot to get the fields with content into view. It would be great If I can hide empty fields so that they're only visible in edit mode. Fields completely in capital case shouldn't be hidden because they are section headlines from Enpass (I wish, Strongbox/Kepass could have a native headline feature).

Occasionally, I would like to get rid of those empty fields. Maybe a cleanup-feature could be useful.

PS: Sorry for the bad english ;)

Thanks for the feature request @Tekl - We'll have a think about how best to do this.
