New Utility: alternate-node-red-installer

So just let the script run, cd into the resulting master folder and then use npm install --unsafe-perm --production node-red@xxxx where xxxx is the version you want.

Feature request? Would it be possible to add an argument to the installer with the version to have it installed that way immediately, for example when testing bugs on potentially a specific version of NR? Or maybe add this to the documentation on github
