skip_before_filter is deprecated

[ecmrauh]

Hi,
as mentioned here, the usage of skip_before_filter is deprecated and should be avoided. So the following call doesn't work with the current Rails version.

redmine_remote_user_auth/app/controllers/account_remote_user_controller.rb

Line 9 in 6eaf1e7

skip_before_filter :check_if_login_required

Regarding this, I have a related question. Is this call necessary at all? The class AccountRemoteUserController is derived from AccountController where (its successor skip_before_action) is called, too:

https://github.com/redmine/redmine/blob/3aef7783423fc47a987bad6df060ad69a06221dc/app/controllers/account_controller.rb#L27

Sorry, I'm just using this plugin but don't have any Ruby skills...
