Some margin and indentation tweaks in news and NPC dialogs

* Apply indentation after wrapping only in NPC dialogs and chat window,
  since we don't want this in the updater window / news.

* Added some margin around the text in the updater window and NPC
  dialogs, using gcn::Widget::setFrameSize.

* Cosmetic changes to BrowserBox implementation.
