* Updated to ZDoom 4025:
- Do not clear the CF_WEAPONSWITCHOK flag each tic, so that the last setting from A_WeaponReady will carry over until the next A_WeaponReady. Changed P_CheckWeaponSwitch() to clear any pending weapon requests while weapon switching is disabled.
- Removed the BuildString() override that took a char** argv, because it was used nowhere.
- Fixed: BuildString() failed to properly generate command lines for arguments with embedded " characters.
