Add simple movements with /move command

- Determine if we can move to the specified direction
 - Add moving ability to the specified direction
 - Add /move command for triggering moves
 - Add move decomp. into steps (more natural)
 - Add pathfinding routines (still WIP)
 - SO YES YOU CAN NOW WALK USING MCC!!!
