This uses eslint --fix to automatically repair coding style violations.
This commit is scoped to binaries/data/ only, and limited to these three rules:
No manual fixups seem to be needed. I did exclude the fixes it made to
binaries/data/mods/mod/globalscripts/sprintf.js, as that appears to be
upstream file and not something meant to follow our coding style.
In a follow-up I'll add an Coala exclude for that, so that it won't complain again.
