Factor 0.86 released

Factor 0.86 has been released. We took about a week to test it before releasing this time, and it promises to be the most stable release ever. Factor for Windows has a few improvements too, as a long-standing bug with the native i/o has been fixed, allowing Factor to be run in the console while still supporting native i/o with the command:

f -shell=tty

Furthermore, in 0.85, Windows Factor took several minutes to slurp through a 600 MB file; the new version takes five seconds and will speed up again when continuations compile.
