Added water step/land sounds.
Made footsteps toggleable (in case the player is using another mod that adds them).
Added handling of liquid terrain on all actors that need it.
Fixed dual enforcers breaking after level transition.
Fixed some refire issues caused by the use of the Resurrect cheat.
Made guided redeemer missiles explode on player death.
Replaced pure particles on pulse gun effects with actor particles.
Implemented proper HUD rendering, along with toggling and resizing. Works just like in UT now.
Added "extended" version of the Beta menu music, quickly put together in OpenMPT. I really like it.
Added M_DOOM graphic and changed the titlemap texture.
Made various screen graphics additive now that I know how to.
Separated pickup and first person brightmaps for Pulse Gun, this is needed for beta skin packs (there will be skins for the Pulse Gun, Redeemer and Impact Hammer).
