subworlds

Closes #144.

This builds upon portals support (#1356)

Demo

scripts/play.sh --scenario data/scenarios/Testing/144-subworlds/subworld-mapped-robots.yaml --autoplay --speed 2

Future work

• Augment portal definitions with an optional "relative orientation" attribute, that can turn the player around when passing through the portal (Automatically re-orient robot when passing through portals #1379)
• Specify whether portal performs instant transportation or whether move down is required (Optional explicit up/down movement through portals #1368)

@byorgey have a look at your leisure. There's a bit more work to be done, but I'm excited to say that this "works" and passes the test suite.
