time

Fix Confirmation dialog page to allow title change

In configuration dialog page title variable was not set so title was
always "Please Confirm" instead of the parameter sent to function
Update Confirmation Dialog to handle variables

Title, Line 1 and 2 now support variables described in ui.h like %x1
Line 4 does not support as no need right now
Add Zprobe(AutoleveL) in Configuration menu

Add Zprobe function from menu, proposing/asking user to clean nozzle and
plate first then heating bed and extruder then doing Zprobe, when done
it propose user to save result
Unlike G32 command, this function handle failure and put nozzle in safe
position what ever happen to avoid any hit on plates, this function does
not take in account Zprobe end script but only Zprobe start script,
anyway both are are empty for DaVinci so no real impact.
Same for Z_PROBE_REPETITIONS it is not taken in account but it is set to
1 for DaVinci so not impact neither, failure point is not specified -
this can be added later.
