Subject: Add basic PEP managemend UI to EditAccountActivity

EditAccountActivity now show own fingerprint, and gives an option to
regenerate local keying material (and wipe all sessions associated with
the old keys in the process).

It also now displays a list of other own devices, and gives an option to
remove all but the current device.
