Introduce SharedValuePool, a little helper class that restores implicit
sharing on objects that are received in great numbers but only with a
small set of possible values. Use it for item mimetypes and flags,
reducing their memory use from O(n) to O(1) for larger folder listings.

Comment out the set version of SharedValuePool, currently unused and the
template code to switch between the set and vector version fails to
compile on Mac OS and Win CE at least.
