sektorcoder SVN Code

Improved session management. Need to do two IMPORTANT things.
1. Study and rewrite php sessions for login security
2. Create an abstract login class to use as basis on Login and Index states.

Login control and sessions enhanced. Better logic

Login statuses and session manipulation extended. Security (.htacces) enhanced with url rewrite.

Finished validation of datatypes. Changed index asp a little bit to look better.

Datatypes & validation tests

Many changes, most notably DATA TYPES and DATA TYPE VALIDATIONS

Important: Changed Images , Videos and Icons folder locations and put into Media,
seemed a good idea. If there's a problem we can roll back to the default.

Working login.

Need to change/check in the future:
Ajax logic everywhere,
Security conventions on every page,
Stabilize OO Class design conventions
