Misc cleanup
Restructuring.
Combined the full and subset display.
Removed the flicker by making the components mutable.
Rewired clipwarn, renderstus and enhance.

Problem with enhance stil....not sure what.
Fixed enhance button.
Fixed flicker on transfer-only change.
DRAFT Subset aggregates wrapper (saves a copy on enhance).
Combined subseting to a single wrapper.
Removed subset task.

Does it in the full render or as a function call (it is just a wrapper now).
Modified overlay/enhance display.
Corrected comments.
Progress bar (optionally) moves more often.
All MemMapLists share the same thread pool for parallel bounds calculations.
Fixed subset-of-subset failure on mem-mapped list.

I'm not particularly HAPPY with the fix.  It ties the MemMappedList tighter to files where I want to move more towards byte-buffers.  However, it fixes the problem for now.
Int-backed yields faster access
Primitive-specific aggregates implementations (takes 30% off of renderspeed on Wikipedia...)
Cleanup of primitive-specific aggregate implementations and some documentation.
Fixed error in toString when int/long values.
Made to be global transfer unles a selection is made (used to be view-relative.
