Improvements to the Dialogue Text Displayer

There are two common issues I've run into when using the Dialogue Text Displayer that can make it fiddly to drive logic via prompts.

Powering the gadget OFF via keyframes does not remove the text from the screen once it's active. This seems unusual considering most (if not all other logic) can be powered down in this way.

Request: Please allow us to fully power it down using keyframe or wires into the power port.

There is a small highlight(?) delay when using a button prompt to close text even when the Highlight Mode bar is set to 0. I think this is to allow the highlight to play out when selected. However it seems to also delay the signal being passed through, and other logic can cancel it before it's complete.

Request: Please allow us to fully turn off the Highlight Mode visuals and allow the signal to be sent immediately. 

Thanks
