- made Teleport_NoFog compatible with Hexen and Eternity.

Browse source 
ZDoom defaulted to Boom's (buggy) angle adjustment.
Changed it so that
 * Mode 0 is like Hexen, performing no adjustment at all. This still should match all known maps using this special.
 * Mode 1 remains unchanged.
 * Mode 2 replicates Boom's broken angle adjustment and is used in the xlat file.
 * Mode 3 implements the correct angle adjustment that Boom originally intended.

 (Note: Should some map require something different it should be handled with compatibility.txt instead of reverting this back to the broken way it was before.)
