Project:Ruby/Ruby 1.9 deprecation

Upstream support for Ruby 1.9 has ended on 23rd February 2015.

Deprecation plan

 * Get ruby20 and ruby21 package coverage up to the same level as ruby19
 * Stabilize packages with ruby20 support
 * Default Ruby target for new installs to ruby20
 * Package.mask and remove ruby19-only packages

For further information please also check https://bugs.gentoo.org/show_bug.cgi?id=536852

Packages that are currently only available to ruby19
These need to be checked, if ruby20 or later is possible.
