Reorganized layout and appearance of rooms list page. Creating a new room uses a dialog prompt for the room name, which is preset to whatever your last room name was. Removed dotted rectangle around selected cell in rooms list. Removed bug where gamecfgwidget would be in master mode when joining a game as a slave. Can now join selected room when return is pressed. Can also move room selection while room search box has focus.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
