Can't bind NON-gameaction to controllers

[masher42]

First, thank you for making this modification. This is by far the best game I have played on my Vive yet. I am at my third play-through right now :-) Can't get enough !

I wanted to be able to toggle the hud on/off. So i added

bind "VR_RIGHT_DPAD_RIGHT" "toggle g_showHud"

to my autoexec.cfg, but it doesn't work. Looks like only "game actions" can be bound to the motion-controllers. It would be great to be able bind other kinds of actions too.
