mahoro 0.2 - Ruby 1.9 compatibility!

Mahoro is a Public Domain Ruby interface to libmagic.  It is in use by
several existing libraries and now updated to work with Ruby 1.9.

This project was originally started by Shu-yu Guo but is now maintained
by Eric Wong.  Please email Eric <normalperson@yhbt.net> for any
questions/issues/bug reports/comments regarding Mahoro.

* add gemspec for RubyGems.org

* use xfree() instead of free() in for GC destructor
  This allows Mahoro to run properly under Ruby 1.9 that
  is built with CALC_EXACT_MALLOC_SIZE.

* Minor test cleanups

* update for Ruby 1.9 compatibility
