Saving G29 Bed Level Correction Matrix to EEPROM

[AbuMaia]

does the code behave as expected and do what people wanted? Can you add the semi-colon and invoke the EEPROM Print so we can check if the matrix prints OK ?

So I suspect we need a blank line (or one that just says echo after the last line of the matrix. But I kind of hate to add blank lines of output. Opinions anybody???
