Listen for Reporter to flush bundle, then clear the cell count on next
scan.
Reduced LRUCache size overshoot back to 0 from 100 as it caused heap
to grow too large.
changed the subsample to 2 so that map tiles consume less heap memory
Timer was calling broadcastsync on the timer thread, and in general,
doing a bunch of other thread-unsafe access. Made this thread-safe
through use of a handler. (A handler is on the thread where it is
created).

Minor cleanup items for developer screen
Stop invoking .toString() in a log.debug statement.
Updates to testcase as flush() will force the bundle to be null and the Reporter needs a handle to a live context object instead of null.
