String changes made in Orca

[Joanmarie Diggs <joanmarie diggs gmail com>]

Our apologies for a few very-last-minute new strings.  One truly new one:

  #. Translators: The "default" button in a dialog box is the button
  #. that gets activated when Enter is pressed anywhere within that
  #. dialog box.
  #.
  #: ../src/orca/where_am_I.py:1464
  #, python-format
  msgid "Default button is %s"
  msgstr ""

And a few at the request of Kenneth Nielsen (please see bug 469615).  In
particular, we added Q_() support and started using it. :-)  Right now,
just to distinguish various uses of "selected".  If we need to clarify
other items, please let us know.

  #. Translators: when the user selects (highlights) text in
  #. a document, Orca lets them know this.
  #.
  #. ONLY TRANSLATE THE PART AFTER THE PIPE CHARACTER |
  #.
  #: ../src/orca/default.py:3172 ../src/orca/default.py:5983
  #: ../src/orca/scripts/StarOffice.py:142 ../src/orca/where_am_I.py:490
  msgid "text|selected"
  msgstr ""

  #. Translators: when the user unselects
  #. (unhighlights) text in a document, Orca lets
  #. them know this.
  #.
  #. ONLY TRANSLATE THE PART AFTER THE PIPE CHARACTER |
  #.
  #: ../src/orca/default.py:5997
  msgid "text|unselected"
  msgstr ""

  #. Translators: this is in reference to a radio button being
  #. selected or not.
  #.
