Move the timings-specific pieces of the buildbot infrastructure into

the trunk/timings directory.  We'll map them into the buildbot directory
using svn:externals.  This will let us keep all the pieces of a timing
configuration, including its buildbot pieces, in one place, and will
let us simplify the Master initialization (since it will be able to look
on-disk for the configurations for which it should set up buildbot steps,
instead of querying the SVN server).
