- New pin state realtime reporting feature. Instead of `Lim:000` for limit state reports, the new feature shows `Pin:000|0|0000`, or something similar. The `|` delimited fields indicate xyz limits, probe, and control pin states, where 0 is always not triggered, and 1 is triggered. Invert masks ARE accounted for. Each field may be enabled or disabled via the `$10` status report setting. The probe and control pin flags are bits 5 and 6, respectively. - Remove the now deprecated `REPORT_CONTROL_PIN_STATE` option in config.h - The old limit pin reports `Lim:000` may be re-enabled by commenting out `REPORT_ALL_PIN_STATES` in config.h. - Incremented the version letter (v1.0c) to indicate the change in reporting style. - Replaced all bit_true_atomic and bit_false_atomic macros with function calls. This saved a couple hundred bytes of flash.
