Apart from applying the points described in readme_moodle.txt, the following
changes have been done too:
- The parameter $folderName from the method libraryToString() have been removed
and a new method, libraryToFolderName() has been added to the H5PCore API.
References to libraryToString() with the $folderName set to true have been
replaced to the new method.
- missing-main-library has been added and replaces in some cases to
missing-required-library.
- The framework saveLibraryData method must be called before saveLibrary
(h5p.classes.php file has been patched to leave the original order because
libraryid is required to save the itemid).
- The getLibraryId() method from H5PCore has been rewritten to use MUC, in
order to avoid PHPUnit failures.
