Changed files: common/vid_<system>.c, common/vid.h, uquake/menu.c, qw_client/menu.c, AUTHORS * Corrected the menu system to work as intended (extra options depending on used vid_<system>.c file) ATTENTION!!! I'm not able to test for the different *nixes, please check if I changed everything correctly, plus the previously disabled extra options have to be checked too. Thanks. * Fixed where you couldn't get back from console when accessed through menu (taken from qw_client) * Fixed menu bind problem in QW ( now \"%s\" )
