[bug] laser distance leniency

[nieknooijens]

the laser distance leniency from the debug menu is not configurable via config and on linux it seems as if it always stays at 1. on windows it defaults to 0.08 and resets after every song. unfortunately my controller only has 15PPR encoders so I want to raise that value to 0.2 and keep it that way. even if it isn´t configurable in the config, at least it should be made static so it doesn't change every time you start a new song.
