It was slightly confusing to have another override for snapping while it is possible
to configure "no snapping" or "all layers" snapping mode in project anyway.
And with the nice snapping toolbar it can be also done very quickly.
QgsMapToolMoveFeature now inherits QgsMapToolAdvancedDigitizing
this allows to specify distance, angles, complex and multiple moves at once
it is now a click and click operation (similarly to the rotate feature map tool): so it can be cancelled once enabled with the right click
When enabled, repeating locks are not automatically cleared when
a new point is added. They are handy when the same constraint
must be repeated for multiple points (eg adding vertices
which are always 50 meters apart)
(fix#12605)
constraint is locked
The previous behaviour was that the constraint had to be "relocked"
if the user manually altered the constraint value in the text
widgets. Now users can edit the constraint value after already
locking the constraint.
