[PATCH] Add an optional encoding arument to Deb822Dict.dump

[John Wright]

In order to support dumping Deb822 objects with unicode objects as values=
,
there is now an encoding argument to the dump method.  This way, you can =
do

    d =3D deb822.Deb822()
    d['foo'] =3D u'=FCber'
    f =3D open('/tmp/testdeb822.txt', 'w')
    d.dump(f, encoding=3D'utf-8')

This should work for any encoding, as long as the encoding can represent =
all
the characters in your Deb822 object.
