LEDs: nozzle light follows the motion sensor, new logo status macro

The motion timeout switched the nozzle LEDs off during prints, motion
switched them off when idle or paused, the timeout counted from the first
movement, and every _status_* macro stopped the nozzle light.

- _LIGHTS sets case light and nozzle LEDs from presence, print state and
  CASELIGHT MODE=AUTO|ON|OFF; the timeout (60 s) starts at the sensor
  release
- _STATUS STATE=... replaces the _status_* macros; logo effects only
  cover the logo LEDs and use REPLACE=1
- heater gauge while heating, print progress, paused, error flash from
  _ERROR, part ready once the bed is cool, dim night mode when idle and
  nobody near, cleaning during BLOBIFIER_CLEAN
- removed unused effects and macros, 12 fps for the toolhead effects
