Build a calcite-bootstrap-theme.css

Hey guys, can we please extract and build out a separate calcite-bootstrap-theme.css?

Bootstrap recommends this approach for applying themes and users will be used to this approach too. Plus it separates our local build from their CDN build so we can get the benefits of their fixes immediately.

If we really need to build our own calcite-bootstrap.css for the work you guys are doing, that's cool, but the rest of our projects e.g. App Templates should probably use the bootstrap + theme approach.

Thanks!
