Contact Diary v1.2.0 release

This version brings quite a few new features, with two important ones.

• The time of the contact is no longer asked. Instead, now the forms ask for the duration of the contact.
• App shortcuts (thanks to GenosseFlosse).
• A section with acknowledgments has been added.
• Some bugs have been squashed, including the visualization of risky contacts only.
• New translations are available
  • Polish (thanks to wasikr7)
  • Finnish (thanks to Mikko95)
  • Indonesian (thanks to hexatester).
• Small fixes in the other translations.
• All changes: v1.1.4...v1.2.0
