added more.fs for people with old terminals.
WORDS and SEE now now respect the terminal size.
a lot of reordering in the Makefile, approaching the GNU standards.
factored NAME>STRING out of many words.
use AC_DECL_SYS_SIGLIST test in configure.in.
removed emitcounter (it was not used anyway).
SYSTEM now unpreps and repreps the terminal.
fixed byg in prims2x.fs.
added NEEDS, ?CSP, !CSP.
rewrote ALIAS?.
