* add Language::Node helper module This adds a language module for Node module based formulas. It contains the 2 public methods `std_npm_install_args(libexec)` and `local_npm_install_args`: * `std_npm_install_args` is intended to be used in formulas for standard node modules and returns `npm install` args for a global style module installation to libexec. * `local_npm_install_args` is for formulas, in which the `npm install` step is only one of multiple parts of the installation process and returns `npm install` args for a default local installation in place. Both methods have in common, that they are * making sure that a working copy of npm and node-gyp from node's libexec is prepended to the PATH (to not rely of a user managed npm) * seting the npm cache to HOMEBREW_CACHE/npm, which fixes issues caused by overriding $HOME resulting in long install times + high disk usage (see https://github.com/Homebrew/brew/pull/37#issuecomment-208840366) * audit: update npm install check for Language::Node * cleanup: remove npm_cache too * doc: add Node-for-Formula-Authors.md
