Subject: [PATCH] Adding node prompt that does not require NVM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are now alternative version managers available, such as volta.sh.
We should be able to show node version regardless of whether you are
using NVM or not. I decided not to add dedicated PREFIX variables for
now, but it can be done later.

We still check nvm first, and if it returns something — we use it.
Only if the output of NVM is blank do we use the new function to grab the version of NodeJS.

There is a caveat — if node is installed with the OS, eg `/usr/bin/node` this
function will pick it up and run `--version` on it, and therefore it will
now be displayed in the prompt.

Tested locally on OS-X/bash:

* with/without NVM
* with/without VOLTA
* with/without system node
