Allow importing of private key strings

Fixes #1021

A top-right menu item now allows `Account Import`.  It has a menu (with one item for now) that allows importing a private key string.

Errors are displayed, and a success navigates the user to their account list, where the imported account is labeled `LOOSE`.
