#1 Implement user access based on sessions

[Joao Simioni]

Improve User Access management – today access is
controlled by Apache, with a .htaccess file. The
intention is to change this behaviour and rely on
cookies (session management) to check if the user is
authenticated – this will simplify a little bit the
user control; also this is a step to allow the system
to remember the ‘last’ access of a user, keeping the
same user preferences used before;
