improve mp chat behavior

* ctrl + enter ignored for starting songs in screennetselect
* minimize will always clear current message and disable typing
* ctrl + enter will unmimize and activate chat input if minimized, or activate chat input if unminimized
* insert will hard hard minimize the chat similar to the mouse click toggles, but will activate input automatically
* pressing "/" will maximize and activate input as needed and auto place a "/" (for fast commands)
* pressing enter while the typingtext is empty will turn off input (basically, double tap enter to disable input)
* delete clears the current msg, since we have no cursor it does nothing anyway and hitting escape diabled
