Spawn Princess

[hartgit]

Describe your changes

Added a spawner for the princess, very bare bones script.

See if we want to backmerge it into the Boss branch to trigger on boss death or if we do it in staging.

I will move the spawner to the Boss room after everyone has tested. In the start room right now for convivence.
