Refactored the mess known as Hook default_url_options in favor of the simpler
:only_path as suggested by splatteal on GitHub.

#2542

Implementing the missing tests now that HookTest has a cleaner setup.

Controller and Views are now tested through the Redmine::Hook::Helper module.

#2542

Refactored the HookTest methods to use Redmine::Hook::Helper instead
of the Redmine::Hook class directly. Redmine::Hook::Helper is the
public API so it should be one that is tested.

#2542

List the Default Columns displayed on the issue list vertically
instead of horizontally so it's easier to read.

#2745

Allow the other format links to appear on the issue list (ATOM, PDF, CSV).

#2779

Fixes "too few arguments" error on activerecord error translation (#2626).

Adds (a maximum of 3) links to project ancestors in the page title (#2788).

Send an email to the user when an administrator activates a registered user (#2656).

Fixed the bug in the OpenID registration where the form wouldn't take a login

AccountController#open_id_authenticate was adding an auth_source_registration
to the session which caused AccountController#register to use the wrong codepath.

#2757

Fixed a bug in the OpenID login when a user signed up with OpenID but hasn't
been activated yet.

When logging in the user would come back to the login page with the back_url
of My Page. This was caused by open_id_authenticate sending the user to My Page
and My Page redirecting the user back to the login page because they haven't
been activated.
