A pretty major update, from now on:
- every config goes into custom data, you don't have to modify anyithing in the code
- you can have a group of of lcds to show information (like "next stop: command center")
- you can have a timer block to trigger for arriving to station (open doors, switch lights, etx) and one for departure (close doors, switch lights, etc)

Have fun, and let me now in the comments if you find anything wrong.

Fixed the direction determination with a more simpler method

Removed the config need for grid mass, now it's calculated automatically
