Allow for caching of compaction scores
...
Potentially reduce the overheads of scoring each file on every run.
The change also alters the default thresholds for compaction to favour longer runs (which will tend towards greater storage efficiency).

Initial re-wording to reflect low-level design changes
...
This might change back again. It is easier to make the KeyStore and TreeCaches to manage more directly the rebuild process. The only issue is whther this would "lock up" thevnode should the vnode ever wait on a response for example for a tree root (when the TreeCache is finishing the load)
