JSON file has incorrect extension

[jimthedev]

Hello hello,

Easily resolved issue here. Bottom line, there is a JSON file in the ui-router repo that has a .js extension even though it isn't javascript. For parsers that assume .js Javascript, this is a problem. The specific file is:

ui-router/config/jsdoc.js

As far as I can tell, jsdom isn't actually used anymore so this could just be removed. An alternative fix is to rename this to .json. Either would be great and would be an immediate fix to the problem. Obviously the parsers also need to be changed to be less brittle, so I am putting in PRs there too.

Thanks.
