CGUI now represents a single 'page'. CGUIManager maintains multiple pages and switches between them. Split the XML files into pregame, loading, session and messagebox pages. Added hotloading of GUI pages. Minor GUI cleanups. (Merge from hg 81862d33780c) This was SVN commit r7214.

* Only one page is active at a time. All events and render requests etc
