Break too long lines and simplify the code
- Add boost_cart:get_rail_groups to get the default rail groups - Remove duplicated code - Do not boost the cart backwards when the brake rail gets activated - Attempt to fix the cart swing problem - Trim tailings and tidy up code - TODO: Document all the stuff
