Foreman » Packaging

Update deface to 1.0.1

Change core Foreman packages to ship nokogiri 1.6.x as a requirement
for deface 1.x.

Set HOME to ~foreman as rb-readline requires it

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.
