Ooze prevention:

Browse Source 
- remove the infinite skirt
- added 'idle_temperature' in Filament Settings as an optional parameter
- the logic is changed: if idle_temp is present, it is used,
  otherwise it uses the old delta value from Print Settings
- TODO: the optional parameter is not well supported in UI
