Initial TypeScript conversion

This is a straight TS conversion, without significant changes to the
API. The work was started by @jason0x43 and completed by @nicknisi.

In addition to the basic conversion, several other project-level changes
were made:

- Move from custom dojo2 to dojo-core, etc.
- Use pre-release TS version of Dig Dug
- Use `files` in package.json instead of .npmignore for package building
- A new intern-dev package is used for all the build lifecycle functions
  (build, clean, lint, etc.)
