Revised core setting structures, changed from 8-bit to 16-bit CRC checksums for improved detection of corruption/version mismatches.

Added option to homing enable setting ($22) for per axis homing feedrates.

!! Backup and restore settings over an update is recommended since all settings will be reset to default. Any odometer data will also be lost.
