Devilblock has arrived

- Very hacky and lazy implementation of an enemy. Will have to refactor
it soon. But I want to have some gameplay to show soon as well

Main thing holding back progress is the handling of the two coordinate
systems. Very unclear how that should be dealt with, like any systems
of this game. Trial and error I guess.
Spawn points

- Map data now including default spawning points
- randomMonsterMovement() now only possible after controlsAllowed is
true. Need to add a callback option for loadMap() so things don’t
happen before the map is initialized
