* ENH: Better error message for __array_ufunc__ not implemented
New behavior:
>>> import numpy as np
>>> class Dummy:
... def __array_ufunc__(self, *args, **kwargs):
... return NotImplemented
>>> np.negative(Dummy())
TypeError: operand type(s) do not implement __array_ufunc__(
<ufunc 'negative'>, '__call__', <__main__.Dummy object at 0x1106df8d0>):
'Dummy'
* check for null errmsg_formatter

This started as a change to make type casting and coercion independent of the type number ordering. While it doesn't finish the job, it at least provides a slight performance improvement due to using lookup tables for the built-in types. I've included a testing script which prints out the cancast and coercion results, and they print out the same before/after these changes on my machine.
