Bug 4151 - Entry metadata not currently reorder-able/reposition-able

Link for bug : http://bugs.dwscoalition.org/show_bug.cgi?id=4151
Made chnges in function Entry::print_metadata() at core2.s2 end. As mentioned in the bug description I have added li id="metadata-$m in code. And also an "If" block is removed just after foreach loop.
