Redesign UI and introduce dark theme (#519)

Caveats:

- The openpgp preference had to be removed because the open-intents developers are too lazy to update their libraries. Over the coming weeks I will be reimplementing a local solution for this instead.

- The autofill dialog is broken but I since it is being worked on in #410 already I'm not going to bother fixing it.
