Adapt Redial to keyboard state array

Because the active key for redial was getting cached as the key being pressed,
Redial would only ever see a key toggled on event for `Key_Redial`. It would
then set `redial_held_` to `true`, but it would never get set to `false` on the
key's release.

This change both fixes it and simplifies the plugin as it is adapted to the
keyboard state array by doing away with unnecessary state variables, including
`redial_held_`.
