fix(translation): Minor source string mods and updates

Minor modifications of source strings and updating the language files.

- Confirming the deletion of snapshots now use plural forms.
- Removed the tooltip from the FileView.
- Integrated (back) elipsis (…) into the source strings because this is relevant in some languages (e.g. read from right to left).
- SettingsDialog crontab section: Use lower case version of hours/days/weeks/… in the crontab section of the settings dialog and fixed a warning message in the same context.
