Update: Change little things in these controllers

This change is because the last commit.
Update: Change other things in views

Because:
- When the view is called by a controller, I can use session directaly in view;
- The information sended to the view (because the last big update) is less, so some variables don't work more...
Debug: Erros in error views

Because of the same last commit: the views that was called by a
controller was good, but the error system don't work with these views -
so, create some views only for error system...
