PronterFace M105 work around (#9227)

Browse source 
PronterFace keeps sending M105 requests during long operations like G29 P1, G29 P2, G29 P4 and G26. The serial buffer fills up before the operation is complete. The problem is, a corrupted command gets executed. It is very typical for the M105 to turn into a M1 (actually... M1M105 is typical).

This causes the printer to say "Click to resume..."

This is a temporary fix until we figure out the correct way to resolve the issue.

More work needed for G26.
