Command other than pick no longer work in git-xbase

[ThiemoVanEngelen]

When performing an interactive rebase with git-xbase, changing the command does change the combo box, but the file written to disk for git does not reflect the new command.
I checked this by also saving the file to some other fixed directory.

I think this regression is caused by commit bd20bc2.
This commit moves a lot of code from decorate_item to decorate, except for the following lines:

           combo.connect(combo, SIGNAL('currentIndexChanged(const QString &)'),
                         lambda s: self.set_command(item, s))

This causes the changes to not be received by the widget item, so it does not update self.command.

By adding the following to the decorate function, things are working again:

        combo.connect(combo, SIGNAL('currentIndexChanged(const QString &)'),
                      lambda s: parent.set_command(self, s))
