fixes #7227 - use and require Ruby 1.9.3 from Brightbox Ruby NG PPA
refs #7227 - require Puppet 3.0.0 and Facter 1.6.12..2 builds on Ubuntu 12.04

When running Foreman or the Puppet master under Ubuntu 12.04 with the Brightbox
Ruby NG PPA, we need Puppet and Facter packaged under /usr/lib/ruby/vendor_ruby
rather than the 1.8-specific path so the 1.9 Ruby will still load them.

Distro packages and older Puppet Labs packages use the 1.8 path, which prevents
us loading these deps, so the newer packages are needed.
Update kafo to 0.6.5
Update installer kafo dependency
Merge pull request #396 from ares/deb/kafo_bump

Update kafo to 0.6.5
update foreman_dhcp_browser to 0.0.6
fixes #7970 - add and prefer /usr/bin/foreman-ruby symlink

Use foreman-ruby for bundle calls especially, so it allows the default Ruby
to vary separately from Foreman's.  Set foreman-ruby to ruby1.9.1 explicitly
on Ubuntu 12.04.
