Area Management

[adketuri]

Add a way for areas to be better managed:
The collective area should have an entry and exit area String, which links it to other areas.

A node can only have 3 children, for each of the cardinal directions (and the entry point)

For defined maps, we need to specify which of the 4 cardinal directions are "teleportable" via a bool and which of those leads to the parent (if applicable, and only one should).

For randomly generated maps, we need to look at the parent for a direction.
