With the release of SD+ you now have control over dials and touchscreen
on top of the usual buttons. Support adds a few new events received and
sent and new configuration objects like Encoder and Layout.

In case of new SD+ plugins, they may be allowed on either a KeyPad or a
Dial (via Encoder). Adding this property `keyPad` allows us to disable
the options of installing an Action to the KeyPad, forcing it to be
Encoder (Dial) only.

Sdplus support

Elgato docs reference DisableCaching, VisibleInActionsList,
UserTitleEnabled which were previously not available in the plugin.
