Issue1501770

The primary implementation is in the PyBoolean.java 
class which is a subclass of PyInteger.  PyInteger was 
refactored slightly to allow PyBoolean to inherit as 
much as possible of the implementation.  Most notably 
references to "value" were changed to "asInt(0)" so 
PyBoolean subclass values would be processed correctly.

Added the Py.True and Py.False statics and changed 
usages of Py.One and Py.Zero to them where appropriate.

Added bool to __builtin__.java and BooleanType to 
types.java

Finally taught the marshaller about the bool type.

Created the bool.expose and bool.derived templates but 
these are not included in this patch as they are not 
stored in the 2.3 branch but are in the jt sandbox.

Testing:
* Ran regrtest.py and got identical results after my 
changes in the number of tests passing (82), failing 
(90), and skipped (97).
* test_bool:  One of the failing tests -- still fails 
but does much better.  The only failure is that bool 
currently allows subclassing -- which it shouldn't.  
There are 5 ERRORs due to missing implementation in 
pickle, etc.  Output:
