3rd-party modules moved, AUP modules & one external library uploaded

I managed to commit my changes to my repo and I now request them to move into the master one. Here are the changes:
- Move the 3rd party modules in sites/all/modules/contrib
- Upload 3 ongoing AUP development modules in sites/all/modules/custom
- Upload an external library (ddcl used by the sexy_exposed module) in sites/all/libraries
