(svn r13042) -Codechange: make a class of CreateScenarioWindow, GenerateLandscapeWindow, NetworkChatWindow, NetworkCompanyPasswordWindow, NetworkGameWindow, NetworkStartServerWindow, QueryStringWindow, SaveLoadWindow. All these classes depended on the 'querystr_d' object which is now put into QueryStringBaseWindow. As a side effect this removes quite a lot of WP macro usages and a few global variables.
