Added nvm standalone shell script. Therefore added check if current node executable is wihtin the auto detected NVM_DIR. If not it will return 'N/A'. So it will not display any 'current version' as long as there is no installed node version within this current NVM_DIR. There is also a 'which', 'root' and 'bin' command. 'which' returns the absolute path to the currently used node version. 'root' prints the absolute path to root path of the currently used node version - the path where the bin and lib dir is. And 'bin' prints the absolute path to the 'bin' directory of the currently used node version.
