Awesome Crosshairs

[XaserAcheron]

Nu-Doom has coolio custom crosshairs for each gun. I'd love to not only make this happen but also use it as a solution for the whole "wtf is my weapon cooldown at" problem that exists currently.

This item is really two features rolled into one:

• Custom crosshairs (i.e. A_SetCrosshair) for all weapons (with modded variants)
• Crosshair-style ACS overlay for cooldowns & charges (i.e. the cool radial thing).

Thanks to Jimmy for pointing out that HudMessage has an option to hide messages on the automap, which makes the second bullet point cleanly doable. Huzzah!

For the sake of progress indication, the overlay system (I call 'em "Crosshair Augments") is all done, so at this point it's just a matter of graphics n' draw calls.
