Subject: [PATCH] Use more lightweight cc-mode scanning function for js2-mode

`scan-identifiers` isn't the best scan-fn (see also #94) as it moves not
just through changed properties. Let's use the cc-mode one, which goes
exclusively through face changes while searching for declared
identifiers.

Fixes: https://github.com/ankurdave/color-identifiers-mode/issues/40
