In-Game HUD - input HUD

[mlugg]

Which component should be improved?

UI/UX

Describe your suggestion

Add an input HUD with the ability to show user inputs (button presses & analog inputs).

Expected result

The way to use this can probably be based directly off of SAR's ihud, since that had a recent restructure which made it super cool and extensible. It can just pull data from usercmds client-side and show them in a Panorama HUD element

Momentum already have a keypress HUD panel; it would be good to combine the two. Hopefully the HUD element can be made extensible enough to cover everyone's needs.

Some rework is needed as per #41
