Add setting/removal of keyring unlock keys to the cli app.

Don't require a key when creating a new keyring.

There will be key setting/removal functions so the step of adding the
keyring and setting a key on it can be done individually.

Add app enumeration and removal to the keystore cli tool.

Rename "default" to "master" keyring as that's what it is.

Also add a well defined name ("Master") for the master keyring so it is
easier to understand what this keyring does instead of displaying an
empty string.

Rename keyring "access/revoke" to "unlock/lock".

The unlock/lock concept just seems easier to grasp and is used in
various similar tools as well.

Make the keystore cli app a BApplication.

We need the app to be registered so that the app info can be retrieved.
