Dehardcode map

* Dehardcode maps (currently not working)
maps need work and proper configs

* Fix bugs
i'm terrible at lua

* Add proper maps and configs

* Fix some bugs
the game at least loads now, though it crashes when you run /start <a map>

* Fix more bugs
The map starts now though you don't get teleported to it.

* Teleport the player to the map spawn on start

* Fix lots of bugs
It mostly works now

* Add butterflies mod

* Another bugfix

* Add fireflies mod

* Add vessels mod (dependency for fireflies)

* Add a sprint mod

* Add a spawnpoint
no more falling into the void

* Update TODO.txt

* Fix the barriers being offset by 2
Also add more dependency mods
