Some work in progress here.

- Upstreamed GetClipAmount() from Doomreal, for inter-compatibility.
- Fix missing unique pickup messages for clips and single flak shell.
- Implement ice death support.
- Fix frictionless corpses sliding around.
- Add support for a Red Heretic key, should work with any custom maps that use it.
- Added anti-bd feature, thanks to Skerion for letting me use this hilarious video.
- Fixed missing drown sound for Female skins.
- Added missing Redeemer altfire sound.
- Fix damage scaling of Biorifle alt.
- Flak Cannon altfire has been adjusted so it fires faster and reloads slower, like in UT.
- Voodoo dolls can now produce liquid splashes.
- Pain and death sounds will always be overriden by drowning when underwater, like in UT.
- Add player portraits to each class for the settings menu.
