Is your feature request related to a problem? Please describe.
Im building a little utility library ForgeRocket-ignite for CS_common to patch Rhino environments with Lodash like convenience and a more es6 compliment std library among other tree shakeable options.

The library works:

1. customize
2. build
3. deploy
4. inject selected feature(s) to the selected script(s)

Frodo is a key actor in this, as it is the engine for most remote interactions, ignite itself is just the wizard and cli clients

The problem, This is JavaScript decision-node only library, I need to be able to filter out the groovy and the N/A JavaScript giving me only relevant JavaScript scripts to inject this library/its features into

Describe the solution you'd like
case: I want all JavaScript > Decision Nodes
frodo scripts --list --language=javascript --ofType='decisionNode'

Describe alternatives you've considered
Not doing this and being sad

Want a demo, ask me any time :D
