Add new command line switch: -aux <empty|std80|ext80|rw3> Add 6502/65C02 x normal/debugger alt read support for CPU emulation (#1353). Fix bug in MemReadFloatingBus() reading from mem[] - no good, if MF_AUXREAD is set. Support odd 80-col text video mode when aux slot is empty: . add a new videoMode flag for VF_80COL_AUX_EMPTY. Correctly support 80COL & DHIRES soft-switches when aux slot is empty or with std80 card. Support VidHD's SHR with -aux <empty|std80>. Save-state: support aux slot empty or with std80 card.
