Completers

The scaffolding for custom completions @Screwtapello and community any improvements you can see are welcome (awk was necessary due to hang/parse-time).

Small additional benefit is a list of unknown/unfamiliar or what was it again? Close match imports that can be reviewed or copied onto system clipboard and pasted into the java api search field to read the documentation. https://docs.oracle.com/en/java/javase/15/docs/api/index.html
