GCI2012: Improve Game Configuration Widget - Refactored mapmodel+datamanager to have two separate map models for static and mission maps, and then three static MapInfos in MapModel for the three special maps (random, maze, drawn). - Created theme selector dialog. - Created seed view/edit dialog. - Enlarged start icon on pagemultiplayer and pagenetgame, and added Start.png. - Moved "Settings" button on pagemultiplayer and pagenetgame from middle of page to page footer. - Added "load drawing" button to mapcontainer widget. - Map preview is no longer the randomize button; The randomize functionality is now in a button of its own. - Map preview no longer grays out (isn't disabled) when in slave mode. - Seed is now viewable and copyable when in slave mode -- but not editable. - You should now use the property master (isMaster() and setMaster()) on gamecfgwidget and mapcontainer instead of the enabled property. This is because some widgets (e.g. "view/edit seed" button and map preview) shouldn't be disabled, when all other widgets should be. - Added mission map descriptions w/ locale support in INI format in mapname/desc.txt if applicable. Use '|' for line break.
