G91.1 support. Fixed a config.h option.

Browse Source 
- G91.1 support added. This g-code sets the arc IJK distance mode to
incremental, which is the default already. This simply  helps reduce
parsing errors with certain CAM programs that output this command.

- Max step rate checks weren’t being compiled in if the option was
enabled. Fixed now.

- Alarm codes were not displaying correctly when GUI reporting mode was
enabled. Due to unsigned int problem. Changed codes to positive values
since they aren’t shared with other codes.
