Fixes issues for programs containing extended M-codes using single meaning words (which they as a rule should not do). Added core support for spindle encoder binding to spindles. Added sorting of spindle report: enabled spindles are sorted first in order of spindle number, disabled by type then spindle id. Changed realtime report to report spindle number instead of spindle id on changes in the |S: element.
