Add bower.json to chai-spies package

[rcchen]

Fixes #13

@rcchen thanks. Could you please remove the version field from the json, as bower does not use it and its a pain to maintain anyway.

[rcchen]

@keithamus removed the version line, should be good to go now.

Just for personal understanding, bower relies on Git release tags for versioning, correct?

@rcchen yup! @kkirsche has the deets over in chaijs/chai#468 - linking to an SO post: https://stackoverflow.com/questions/24844901/bowers-bower-json-file-version-property:

Bower currently ignores version from bower.json.

If the version in bower.json doesn't match git tag, you get a warning, and the version entry in generated .bower.json is fixed (version in bower.json stays the same).

Among others that's why bower plugins should consume.bower.json instead bower.json.

You can safely remove version from your bower.json. Bower only respects git tags.

Most probably it won't be used even in the future.
