Admin area: doesn't show a note when it's empty

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/12636

Remove user from groups when they are removed from LDAP

Fixes #159 

Currently, we only update user permissions if they come back from LDAP
as a valid user. I refactored some things in the `access.rb` file so we
update permissions no matter what. Now the user is removed from groups
and admin access is revoked, in addition to the previous behavior of
blocking the user.

Add support for ZIP build artifacts for Pages

Omnibus change: https://gitlab.com/gitlab-org/omnibus-gitlab/issues/1057

Downgrade group member role if LDAP dictates

Fixes #170 

If a group link was updated to set a lower maximum role/access level, 
a user's role was not downgraded. Similarly, if the user was moved to
another group where their role should be lowered, their access was not
downgraded. For some reason we were preferring the higher of LDAP or
GitLab access even if LDAP said it should be lower. After this change,
what LDAP says, wins. 

If a user is a member of multiple LDAP groups that are linked with the
same GitLab group, they still receive the highest of all roles.
