This change is largely just moving files with minor tweaks to them to fix, the rest of the commit is build process changes: - The addons/ and test/ dirs have been moved to src/ - The build directory has been removed - TypeScript builds are output in out/, this is where tests are run - The demo now relies on the dist/ build which is performed as part of ./bin/build - Addons are now shipped under the ./build directory
