Fix crash on OK after Save Changes in Tags and Comment popup.

The global variables tagsText and commentText were used to pass
a string obtained from a widget (and thus not malloc'ed), which
caused a crash when the GenericReadout tried to use those variables
for the new value. Fixed by using GenericReadout (which does malloc)
to read out the text,in stead of GetWidgetText.
