Clear stale RAM cache when re-deploying components
Clear stale RAM cache when re-deploying components

We currently store treemachine and taxomachine results in web2py's RAM
cache (as part of the phylesystem-api app). To avoid confusion, we
should clear this cache when re-deploying either of these services. This
is done by simply triggering an apache restart.
