Fixed nested file bug, other minor changes

Fixed a bug when one file was called from another
M111 S2 command now displays time since last reset
M106 'I' parameter now only inverts fan PWM when >0
Non-homing moves when bed probing are now done at max speed
M999 reset command now delays 0.5 second to allow response to be sent
back to browser, otherwise it may retry the reset
