New: several fixes regarding the older versions of Moodle.
Note: Previous version could end up with white screen for Moodle if used on really old version of Moodle. This version supports even Moodle. 2.0.0 release (not just last legacy 2.0.10 release). If you are using that old version - please use this version of plugin instead (and upgrade Moodle - of course :) )
