Cleaning up implementation of isometric camera with optional orthographic projection.

Browse source 
All CVars, mapinfo variables, and playerinfo/playerpawn variables are gone.
A Camera actor named 'SpectatorCamera' is defined in warsrc/static/zscript/actors/shared/camera.zs

The following new flag bits were defined in the 'DViewPosition' struct for use with actor->ViewPos in src/playsim/actor.h:
	VPSF_ALLOWOUTOFBOUNDS =		1 << 3,			// Allow viewpoint to go out of bounds (hardware renderer only).
	VPSF_ORTHOGRAPHIC =		1 << 4,			// Use orthographic projection.
	VPSF_ISOMETRICSPRITES =		1 << 5,			// Displace sprites towards camera and don't billboard (drawn from isometric perspective).

Basically, spawn a SpectatorCamera actor with the appropriate flags and set it to player.camera.
See example template: https://www.mediafire.com/file/fv8rytayjt9l6g1/isometric_actor_wads.zip/file

Has been tested with multiplayer death and disconnection (and respawns). Not tested with portals.
Still only works with hardware renderer (mostly). But should be compatible with older mods and libraries.
