[PATCH] gitk: use user-configured background in view definition dialog

Have the text fields in the view definition dialog (View->New view...)
use the background color as configured through the preferences, instead
of hard-coded 'white'.

This was suggested by Paul Wise through http://bugs.debian.org/457124
