Allow downgrades

[TimofeyBiryukov]

Currently you can only install node on a clean machine or when node version is greater than currently installed, discussed here.
allow_downgrade set will enable downgrading node version.

I'm still using this fork and like to see this merged.

I switched to this role, which supports downgrades:

https://github.com/andrewrothstein/ansible-node

It also doesn't require third-party repos.Those third-party repos in turn require more packages to be installed to support third-party repos.

The alternate role downloads and installs directly from Node.js.

Minimum complexity.
