Fix bug #9966 ([CEF 2171] JSLint doesn't work) - Switch to a private fork

of JSLint with the bug fix cherry-picked in so we're not stuck upgrading to
a much newer JSLint which has the fix but is significantly stricter / less
configurable.

Note: you must run `git submodule sync` in order for the submodule URI
change to take effect.
