Initial import of ruby18 package; Ruby 1.8.1 + several security fixes.

	Ruby is the interpreted scripting language for quick and
	easy object-oriented programming.  It has many features to
	process text files and to do system management tasks (as in
	Perl).  It is simple, straight-forward, and extensible.

Detail changes from Ruby 1.6.8 is huge and I know details in Ruby's site.
