Clarify the 'too many alternate clients' messages. Gamepad movement should respond to +speed. favour fte's nq protocols over dp ones when both are supported by the client, to boost compat with qss. try to generate proper utf-8 filenames from player/team names when recording mvds, instead of bad char encodings. Fix loading saved games with splitscreen enabled. pr_dumpplatform can now optionally filter symbols via some specific external files, adding deprecated tags for any symbol not also supported by DP and QSS. Rework CSQC globals to use macros, to ensure completeness and consistency. rework sv_csqcdebug to use special svcs. This should make it more robust. Fix some scary warnings when vid_reloading the vulkan renderer. Fix a possible segfault from opengl+rtlights. Mousewheel will now interact better with engine menus. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5757 fc73d0e0-1445-4013-8a0c-d673dee63da5
