Subject: Refactor trust key ui and show in account details

Refactored the trust key row UI element so it can be used in multiple
places. It now also uses a slider to toggle the trust state, and the
redundant trust state description was removed.

EditAccountActivity now shows the keys of other devices associated with
that account.
