Bug fixes.

- G38.x was not printing correctly in the $G g-code state reports. Now
fixed.

- When investigating the above issue, it was noticed that G38.x
wouldn’t show at all, but instead a G0 would be printed. This was
unlike the v0.9j master build. It turned out volatile variables do not
like to be defined inside a C struct. These are undefined on how to be
handled. Once pulled out, all weird issues went away.

- Also changed two ‘sizeof()’ statements in the mc_probe() and
probe_state_monitor() functions to be more robust later on.

- Updated the commit logs to individual files for each minor release.
Forgot to update the generating script to account for this.
