Install dev aware stubs

[mxcl]

Example stub:

#!/bin/sh

dev_check() {
  [ -x /usr/local/bin/dev ] || return 1
  datadir="$HOME/Library/Application Support/pkgx/dev"
  local d="$PWD"
  until [ "$d" = "/" ]; do
    [ -f "$datadir/$d/dev.pkgx.activated" ] && return 0
    d="$(dirname "$d")"
  done
  return 1
}

if dev_check; then
  eval "$(dev --quiet)"
  [ $(command -v node 2>/dev/null) != /usr/local/bin/node ] && exec node "$@"
fi

exec /usr/local/bin/pkgx/nodejs.org/v1.2.3/bin/node "$@"
