Updated inputs, iso-639-2 auto install on any OS

Updated for 1.104 beta to support inputs.
change install_packages to yes to automatically install the node_module that is required for this plugin.
ISO-639-2 node module can now be installed on any system automatically!
Only tested on Linux but should hypothetically work on other OS too.
