Documentation suggestion: manipulate atom PATH to include current nvm environment

[cemerick]

https://github.com/nwolverson/atom-ide-purescript/issues/75#issuecomment-213293057 provided advice to start atom from an nvm-configured shell in order to get the correct $PATH.

An alternative is to capture the $PATH from a shell after being configured by nvm, and use that for process.env.PATH. Adding this to my init.coffee allows me to start Atom per usual from the e.g. ubuntu dock, but still have atom-ide-purescript pick up the installed executables it needs:

require("child_process").exec("bash -c '. ~/.nvm/nvm.sh && echo $PATH'",
  (e, out, err) -> process.env.PATH = out.trim() )

I don't know if that's something that can be safely added to an Atom plugin (probably not), but perhaps might be worth a README / wiki addition.

Thanks for the great plugin! :smile:

Yeah I don't think that kind of magic belongs in a language-specific plugin, but certainly would consider a PATH override as an option.

Feel free to PR some docs on this
