Changes

Attribute "engine_brake_positions" added to engine_data"accessory_engine_data". It works in conjunction with new inputs for engine brake increase/decrease in same way as retarder.

Attribute "name" in "direct_gearbox_config" is shown in game (options/control/layout selection) if defined. Furthermore, attribute "name" was also added to "direct_gearbox_gear" so each gear definition can have one. These names are displayed in game and override anything defined by transmission_data "accessory_transmission_data" or default generated by game. Attributes "trailer_brake_stick_anim" and "trailer_air_stick_anim" added to "accessory_interior_data" unit. They handle animations of trailer brake and air supply knob respectively. To silence warnings in UI units/defs, remove following obsolete attributes from your modded UI scripts: child_nameless, p2p_pml, name, tooltip.
