Changes for Unix::Uptime

0.37  Tue Dec 14 23:25:05 EST 2010
    - Unify support for all BSD derivatives, using XS, and falling back
      on using the '-b' flag to sysctl, which is a bit more portable
      than the standard output.
    - Add a sample script that sorta emulates the output of the
      uptime(1) command.
