small fix for minimum mass and UI float display precision changes

testing now against being smaller than minimum mass 0.001 and setting it to 0.001 instead
of testing against 0 (useless with float)
adapted displayed UI precision with breaking threshold, cluster breaking threshold, breaking distance and cluster breaking distance.
