[Calendarserver-maintainers] Bug#504557: Even better: depend on twisted instead of conflicting with it

I thought of an even better way: Install only the modified twisted-web2
and twisted-runner in /usr/share/pyshared/twisted-calendarserver, depend
on the other standard twisted packages that you need (like
twisted-core). Then have the post_install create symlinks from
/usr/share/pyshared/twisted-calendarserver to the standard twisted
modules that you need.

This way you profit from the standard twisted packaging work without
conflicting with user expectations or any twisted packages.
