Plugins VoiceControl

Fixes an issue whereby the plugin did not restore trigger action receiver atoms correctly when saved as part of a subscene.

Fixes the issue of the plugin always loading in the active state even if the scene was previously saved with the plugin disabled.

Update to fix plugin disable/enable checkbox not working.

The Head Up Display (HUD) warning feature when VaM's Desktop window loses focus is now optional.
The warning will still be sent to VaM's message log regardless of HUD setting.

Added plugin demo scene.

Bugfix release. Trigger timers fixed.
