Editing, finally!

• Using REST again. First start with base:

sub create : Chained('wiki') PathPart Args(0) ActionClass('REST'){
    my ($self, $c) = @_;
    unless($c->user_exists){
        $c->session->{login_from} = $c->req->uri;
        $c->flash->{message} = 'You must log in to edit.';
        $c->res->redirect($c->uri_for('/login'));
        $c->detach;
    }
}

• If no user, redirect them to login.
• Login remembers where they came from.
