Make fake spawns for d1_town_02, and d2_coast_07

[Pinsplash]

In normal play, d1_town_02 or d2_coast_07 are entered twice, from different places. This is a problem for the effect Restart Level, because if the player is on d1_town_02 or d2_coast_07, they would have to go through both d1_town_02 AND d1_town_03 or d2_coast_07 AND d2_coast_08 again, which is too harsh. For d1_town_02, we'd rather spawn at the staircase close to d1_town_03. For d2_coast_07, we'd rather spawn at the door to the bridge with the forcefield already turned off.

The process for fixing up spawns has been established, I just need to devise a foolproof way to detect which map the player came from.
