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.
