Prepare for 1.0.0-beta.1 release.

- Update `broccoli-typescript-compiler` to 2.0.0 (non-beta release).
- Drop remaining references to tsconfig from `lib/typescript-preprocessor.js`,
  since `broccoli-typescript-compiler` now handles that.
- Update blueprint for tsconfig:
    + generate sourcemaps
    + add `outDir` so sourcemaps work
    + set target to es2017 (let Babel do its thing)
- Update the syntax of index.js to use object method syntax.
- Bump the default installed version of TypeScript and the typings.
- Bump the version to 1.0.0-beta.1!
