This also commits the first working version of WQ based maker to CCTools.
When running wq_maker, the workspace of the worker was not cleaned up if the
worker process was sent a SIGINT. The reason - each task at the worker creates a

files are deleted before their symlinks leading to dangling symlinks. This
commit fixes this bug.
Remove extension in wq_maker.pl.
Add the cctools copyright boilerplate to wq_maker.
