Manifest parsing

AICC, SCORM1.2 and SCORM2004 have different manifest definitions. I've splitted the scorm library in 3 sublibraries (one for each type).
AICC and SCORM1.2 are almost completed but SCORM 2004 need many adds for parsing all the sequencing definitions.
It may be a good idea to have for both SCORM type a standard parsing library with an array that contains just define what is the CAM (Content Aggregation Model) of each type.
This sub-task is joined with the db upgrade and the validation sub-tasks.
At the moment the SCORM module use a class to provide the real XML file parsing; there are no problems to use the xmlize library.
All the CAM definitions are available from ADL site (www.adlnet.gov).
In these days they will release the 3rd edition of SCORM2004 documentation.
