Use only one time parameter when quering multiple pages

If a resource has multiple pages the script will use `next` value to retrieve next page.
Because all requests are done with datetime append to url (probably to avoid caching) `next` containes that link.

`https://api.github.com/repos/user/repo/issues/events?per_page=100&1409248439577`

Second page will be requested by appending a new datetime, so we'll have something like

`https://api.github.com/repos/user/repo/issues/events?per_page=100&page=2&1409248439577=&1409257105342`

Third page url will contain 3 datetime stamps and so on. At some point this will rise an error as browser (and server) has a limit for url size. This way it will cut some of the parameters or will simply throw an error.
