Implemented synchronization message output for NanoDLP printers (nanodlp.com).
If optional feature is enabled in "configuration_adv.h", Marlin will ouput "Z_move_comp" string to serial after completing any G0/G1 Z-axis movements. This feature is used by NanoDLP to synchronize Z-axis movement with projector exposure in DLP stereolithography printers.
It was already patched on some forks from previous versions (https://github.com/mUVe3D/Marlin-mUVe1DLP-Running, https://github.com/WheresWaldo/Marlin_KLD-LCD) but never contributed back to the original code and implemented as optional configuration option.
Would be great to see it integrated in previous versions, so NanoDLP users will be able to use up-to-date versions of Marlin.
