Complete migration to Gulp 4, add linux32 support

- Remove usages of runSequence(), which doesn't work with Gulp 4,
using gulp.series() instead.
- Add support for linux32 builds
- Add new --platform argument for building only for a single platform
(e.g. --platform=osx64).

Fixes build problems introduced in #527
Fixes #531
