This fails to build on modern versions of Node. Gulp and Babel are 1 major version behind.

I tried to build this on Node 23.9.0 and ran into several problems:

Babel 6 is old (Breaking changes)
Gulp 3 is old (Breaking changes)
Sass depracation warnings happen on every build.
Lots of outdated deps.

I was able to update these packages and fix the breaking changes locally. PR inbound.

Thanks, truly appreciate it, currently swamped but I have some time I'll take a look.
