Ray-caster: don't bother clearing the screen

overdraw the previous frame.

Automatically generate externals.js from package-lock.json
...
This commit adds a utility to parse package-lock.json and write the proper
contents of externals.js to standard output. In addition, if the utility
(src/helpers/pkglock_to_externals.litcoffee) is invoked with a --doc option,
it instead emits a Markdown bulleted list of all of the external dependencies.
