sektorcoder SVN Code

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
