Config: Separate beam.routing.r5.suboptimalMinutes into two parameters

[HoneyTauOverTwo]

beam.routing.r5.suboptimalMinutes is used in two different ways inside SuboptimalDominatingList.java: Its value is used directly only for comparing routes with the same access mode, for routes with different ones the value used is 5 times this one.

As suggested in the comment (linked above), separate this parameter into two: suboptimalMinutesSameMode and suboptimalMinutesDifferentMode.
