Fix merge errors on CHANGELOG

API: Events paginate

Updated the api method for /project/:id/events, to use the paginate method instead of limiting and offsetting the recent events in the method itself.

This will also change the first page to be 1 instead of 0, but using 0 will still work and will give back the first page.
This also add's the link headers (next/first/last).

Bump Docker build to GitLab v7.9.1

Upgrade GitLab from v7.9.0 to v7.9.1.

See merge request !476

During merges (d554070a and 497fd75d) changelog was "damaged", I restored the tagged 7.9.1 and added the required changes about 7.10.0 (unreleased). I think we need to ensure all PR are rebased on master before merge.

LICENSE year update

Remove the email patches link for merge commits

Rugged's `to_mbox` method doesn't work for merge commits, so don't display the option to download them as email patches.  This is part of the fix for #1878, and gitlab/gitlab_git!27 allows a plain diff to be generated for a merge commit.  Together these changes should prevent the 500 errors described in the issue.
