When creating or editing a report, the icon file upload field filepicker never fully loads due to invalid requires in edit_report.html

this:
'requires' => array('yahoo','event','dom','element','connection')

causes js errors that mean the filepicker never loads - if you replace it in both locations with:
'requires' => array('event','dom')

the filepicker loads... but the files are never saved - it looks like the filehandling for 2.x hasn't been completed in the code.
