Fix trait composition test in Monticello which could fail in some circumstances.

Let NumberParser test auto-detect whether lowercase digit letters are allowed or not, and then disbale non-10-based floating point tests.
This make the tests green again.

Cache well known digit values in NumberParser for speed.
Testing the base as of previous implementation was not a good idea, because some Unicode characters could have a digitValue < 10.

1) Cache Character DigitValues to gain some speed.
Warning: continue parsing lowercase digits, though it was not consensual.
Note: class var initialization testing will be removed in nxt release. It's only an upgrade guard.
2) Avoid using size == 0

Speed-up Character digitValue PART 2.
Now get rid of class var initialization guard.
Also use value instead of charCode to reach almost a x2 speedup (5x for lowercase).

Use Character>>digitValue..
Now that it is fast enough, there is no point in replicating the algorithm.
