eliminate need for global access to resource manager in uiwidget objects
* dialog.h, dialog.cc (QUIWidgetCreator::m_octave_qobj): New data member.
(QUIWidgetCreator::QUIWidgetCreator, MessageDialog::MessageDialog,
ListDialog::ListDialog, InputDialog::InputDialog,
FileDialog::FileDialog): Accept reference to base_qobject argument.
Change all uses.
(FileDialog::FileDialog): Access resource_manager through local
base_qobject object instead of using global __get_resource_manager__
function.
