Lintian check for Ruby PKG

[Jonas Genannt <jonas.genannt@capi2name.de>]

Hello,

as discussed in the Ruby Bof on Debconf, I have written Lintian checks for our Ruby PKG:

	https://github.com/hggh/ruby-lintian

The lintian checks includes the following three checks:

 * old naming schema (libfoo-ruby) if it's no transitional package
 * depends on ruby1.8
 * depends on ruby1.9.1


These are my first lintian checks, please feel free to comment.

Thanks,
	Jonas
