Decompiled CONFIG.EXE executable (#533)

* mxdirectdraw: no need to explicitly add a terminating '\0' in C * mxstopwatch must include LIMITS.H for ULONG_MAX * Add Config app * 88.78% * style fixes * Test more CONFIG things * Add a few assertions on MFC classes * reformat * actionSSSSSSSSSSSSSSS * actions again * decomplint needed a shebang * Fix annotations of Message Map entries * ci: We're building CONFIG.EXE, not CONFIG.DLL * remove ninja.exe * Fix CAboutDialog::GetMessageMap annotation * format reloaded * Fix global CConfigApp object annotation * trigger worflows * ci: request at least python 3 * oops :) * curl CONFIGPROGRESS-OLD.TXT will fail * Forget about actions/setup-python (for now) * Annotation fixes * Config tweaks and MxDirect3d annotations * It's important to compare against the correct file * Introduce common CDialog parent for CAboutDialog and CMainDialog * format * Remove CSerializer --------- Co-authored-by: disinvite <disinvite@users.noreply.github.com>
