More 808x fixed - fixed (kind of) the 8086 lock ups and the DRAM refresh wait states, also further fixed (and cleaned up) prefetch queue operation, applied a few warning fixes, and fixed the behavior of PUSH SP - anything that uses it to tell 808x apart from 286 is now fixed;

Re-added the higher-clocked 8088's;
Fixed PIT timings for 808x CPU's that don't run off an 14.3 MHz crystal;
Fixed CGA cursor half blink rate setting - fixes insane cursor blinking speed in several cases;
DMA now issues DMA refresh DRAM states on every channel;
Gave the 1982 years to the previously emulated PC and XT's names, and added the 1981 IBM PC and 1986 IBM XT;
Redid the PPI DIP switch redout for the PC/XT keyboard controller;
Fixed a segmentation fault in hdc_ide.c that tended to occur on hard reset after switching machines;
Implemented the port 3B8 color disable on the Hercules, Hercules Plus, and Hercules InColor cards;
Fixed the joystick configuration dialog strings;
Fixed a problem that would have prevented win_sdl.c from compiling with logging enabled.
