Make the cache manager report correct values for the object cache size.

_delObject. This could break code expecting to do cleanups before
deletion.

DateRangeIndexes blew up when attempting to store a date far in the future ( > Y2038 ).  This is a workaround.  The real fix would be to come up with a different conversion algorithm or to use OOBTrees to store datum.

Two new methods have been added to WebDAV resources, "manage_DAVget"
