Subject: Handle case when breadcrumb and filelist item overlap and both
 receive a drop.

Build breadcrumb over and out callback in filelist.js and
pass them as options to utilize local selectors of filelist

Re-enable td elements after drop to bread crumb

Fix# drop handler still being called after enable,
it seems that waiting for a short time before re-enabling solves the
problem

* Add explanations for setTimeout re-enable td.filename drop handler
