Change over to the new PropertySlot mechanism for property
lookup. This allows the elimination of hasOwnProperty
methods. Also did some of the performance tuning enabled by this
(but not yet all the possible improvements for function calls,
assignment, ++, and so forth). And also much code cleanup.

Net result is about a 2% speedup on the JS iBench.

Also redid Geoff's fix for the chrashing applet by avoiding a NULL
prototype in the bindings code and using the default of Null()
instead.

Change over to the new PropertySlot mechanism for property
lookup. This allows the elimination of hasOwnProperty methods. I
also did a bunch of code cleanup and regularization of the various
property lookup methods.

Test cases added: Added a test case for a bug I found along the way.
