Added libbe.TESTING (defaults to False).

This flag allows us to skip unittest and testsuite declaration if we
woln't need them.  It speeds up simple be calls a suprising amount.
With Testing=True (the old behavior):
  wking@thor:be.wtk$ time ./be > /dev/null

  real    0m0.393s
  user    0m0.340s
  sys     0m0.048s
With TESTING=False (the new behavior):
  be.wtk$ time ./be > /dev/null

  real    0m0.216s
  user    0m0.152s
  sys     0m0.064s

This adjustment was inspired by Jakub Wilk's Debian bug:
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=559295
