This script makes a group from selected objects, it inherit orientation from first selected object.
There is a bug when objects are already part of a group, i'll try to fix it...
update 1.1: the bug with existing groups is solved, it doesn't crash anymore but it needs to explode existing groups before grouping, so it doesn't allow nested groups, i'll try to find a work around for next version.
update 1.2: the update 1.1 created some new bugs... version 1.2 should be ok
