wxGUI/vdigit: use 'FloatSpin' widget, which allows you to set the decimal snapping threshold value (#1882)

* wxGUI/vdigit: use 'FloatSpin' widget, which allows you to set the decimal snapping threshold value

Allow setting decimal snapping treshold value (< 1.0) especially for LOCATION
with WGS84 coordinate system with degree map unit (1.0 degree is aproximatelly
111 km).

* Use 'FloatSpin' widget, which allows you to set the decimal query length value
