Bug#395489: Handler for single MULTISELECT questions does not behave correctly when the BACK button is pressed

[Attilio Fiandrotti <attilio.fiandrotti@gmail.com>]

Package: rootskel-gtk
Severity: minor

When a checkbox is activated/deactivated, the corresponding question is 
imemdiatly updated in the questions database, so pressing the BACK 
button won't restore the question's original values.
