Bug 11146: Show a go back link on no permission page

When a user does not have permissions for a page or module, the
authentication page is displayed with message

  "Error: You do not have permission to access this page.".

Most librarians uses the "previous page" button of their browser to
come back on the page they were before trying to get to the
non-permitted page.

This patch adds a button to help coming back to previous page.
It also changes the "Click to log out" link as a button.

Test plan :
- Define a user with staff permissions but no permission on tools module
- Login with this user
=> You get to intranet home page
- Edit URL to go to tools module : cgi-bin/koha/tools/tools-home.pl
=> You get a page with a red error message and 2 buttons "Previous page"
   and "Log out"
- Click on "Previous page"
=> Go get to intranet home page
- Edit URL to go to tools module : cgi-bin/koha/tools/tools-home.pl
- Click on "Log out" button
=> You are logged-out and get to authentication page : cgi-bin/koha/mainpage.pl?logout.x=1
