[ FR ] Remember bed shape

[lukasradek]

The new bed tilting/shaping/visualisation is amazing! And it finally returns correct probing values. Thanks!

One more request... would it be possible to preserve the bed properties between simulator launches? It would help with debugging, since you would be able to set a certain bed shape, which would stay that way even if you recompiled the code.

Thanks!

It always probed correctly as long as Marlin was configured correctly, the fix to detect Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN probably fixed it for you ^^,

Really do need to add a configuration file to store settings.
