The old 'disableCheckedExceptions' branch wasn't a particularly nice distribution/storage model of experimental features. For example, it was hopelessly out of date. Redesigned to a separate experimental directory, along with new build scripts, and rewrite it to the new lombok.patcher model.

Unfortunately it doesn't actually work, just yet. Seems to do nothing at all.
