Title: Add poll-interval to metadata. (From "X-Poll-Interval" events header.)

From the [Events section](http://developer.github.com/v3/activity/events/) of GitHub's API:

> There is also an “X-Poll-Interval” header that specifies how often (in seconds) you are allowed to poll. In times of high server load, the time may increase. Please obey the header.
