Merged contents of tanity-check into sanity-check to do sanity check for both standard
and unicode versions together. Moved the sanity-check script to the test directory

Added ./bin directory for binaries. This includes ./bin/spitbol for standard (ascii) version
and ./bin/uspitbol for unicode version. The bin/spitbol (former ./basebol) is now used to
build the system.

Revised makefile so can now build unicode version with
  make UNICODE=1
instead of the clumsier
  make ARCH=x32-32
Merge branch 'master' of http://github.com/hardbol/spitbol
Update 'make install' to also install Unicode variant (uspitbol).
Update readme.html for 13.10, especially to describe Unicode support.
