qtplasmac g-code filter: do a little less filtering of z moves with <keep-z-motion>

Previously we would remove things like:
G53 G0 Z[#<_ini[axis_z]max_limit> - 0.19685] even when #<keep-z-motion> was active.

Also, if #<keep-z-motion> is turned off, the g-code filter wil ensure the next rapid move gets a Z move up for safety.
