E4M3 map fixes incl. 100% monster kill in easy skill, removed shootable trigger and message of the starting room in deathmatch
When you play Quake's Episode 4 Level 3 (E4M3) you can not kill 100% of all monster in easy skill, as a fiend is spawned but not the corresponding teleporter trigger.
As there are already two zombies at the teleporter on the graveyard, the fiend should be removed.<br>
In the starting room the shootable trigger (at the red window) and the message trigger at the door also appear in deathmatch and are annoying, so they should be removed in deathmatch.<br>
The new entity list fixes this.<br>
