Add Ruby 2.2.0-preview1

rbenv install completion includes definitions from plugins

Show specific upgrade instructions based on environment

Because ruby-build is both a Homebrew formula and an rbenv plugin, some
people end up with both installed. In these cases, executing
rbenv install vs. ruby-build might not use the same install. Users
end up being unsure where rbenv install is coming from and upgrading
it from the wrong location.

This detect whether ruby-build is contained in Homebrew or git and shows
upgrade instructions accordingly.

Peruse /etc/os-release among others when detecting system info

On Fedora, this results in a nice "Fedora 19" identifier and doesn't
show the codename "Schrödinger’s Cat" which is otherwise contained in
/etc/fedora-release.

On Arch, this shows "Arch Linux" where previously we had no info for it
(for some reason, /etc/arch-release is empty).
