- Reorganized all of the status message feedback from both the g-code parser and settings modules to be centralized into two message modules: status feedback from executing a line and warnings for misc feedback. - Pulled out the printPgmString() messages in settings.c and placed it into the new module. (settings_dump() not moved). - Some other minor edits. Renaming defines, comment updates, etc.
