I noticed the old code was replacing two spaces with one space, over and
over. Instead, I changed it to remove all consecutive strings of spaces
just once, using the "+" quantifier. This should behave the same but is
nicer to read and faster.
This sets up ESLint and its config, and disables a bunch of recommended
lints that currently do not pass. Later PRs/commits will fix those lints
and re-enable them.
