Set the 'X-RateLimit-Reset' header

[davebrace]

Set the 'X-RateLimit-Reset' header to the number of seconds until the current throttle expires.

This implements what was proposed here: #2.

Any news about this PR @davebrace? I'm looking for this kind of feature as well.

[davebrace]

@pabuisson No news - waiting for feedback from the project maintainer @jbyck.

We're using a custom fork of this project in production that includes this feature.

[pabuisson]

OK I'm following this PR closely then... and in case it does not merge soon, I'll do the same as you and use a fork of the project. But maybe we'll get some update from @jbyck !

[jbyck]

@pabuisson @davebrace sorry for the lack of communication here. I haven't been monitoring this project very well.

This looks reasonable to me, but the tests are failing in Travis. I'll be happy to merge and make a new release once it goes green.

I actually don't use this myself anymore in any current projects - if either of you are using it, and are interested, I'd be happy to pass on ownership for someone to maintain more actively.
