Modify ECC points to do all math in Montgomery form, rather than
converting back and forth. This gives a 10 to 20% speedup on a Core
i7. In addition, the CurveGFp no longer contains a Barrett reducer,
saving 3 BigInts worth of memory.
Add a #if'ed out alternative to point multiplication using the
Montgomery ladder technique. It runs in (more or less) constant time,
but rather significantly slower than the 4 bit window technique
currently used.
Tweak the window sizes to match the theoretical optimums.
