Subject: [PATCH] Update typings for handlebars

- Add optional options param to parse. This reflects the options param
in the Handlebars source code. Also defines interface ParseOptions,
which includes the options that have an effect on Handlebars parsing.
- Fix duplicate properties in tsconfig.json.
- Fix typo in import in handlebars-tests.ts.

Reference Source:
https://github.com/wycats/handlebars.js/blob/master/lib/handlebars/compiler/base.js#L11

Non-breaking change (new param is optional).
