submissions
One more patch aimed at improving usability of ATutor. It enables group deletion of test submissions by replacing radio buttons with checkboxes and adding a "Select/unselect all" checkbox.
Also it fixes minor bugs found in that area (I've noticed as much as seven of them).
The change has already been included into the trunk for the next release, 1.6.2, while this patch allows users to benefit from it right now.
