Converts an object and returns a ``JSON``-friendly structure.

Considers the following special cases in order:

returns the result of the call to __json__()
* date and datetime objects
returns the object cast to str
* Decimal objects
returns the object cast to float
* SQLAlchemy objects
returns a copy of the object.__dict__ with internal SQLAlchemy
parameters removed
* SQLAlchemy ResultProxy objects
Casts the iterable ResultProxy into a list of tuples containing
the entire resultset data, returns the list in a dictionary
along with the resultset "row" count.
.. note:: {'count': 5, 'rows': [('Ed Jones',), ('Pete Jones',),

* SQLAlchemy RowProxy objects
Casts the RowProxy cursor object into a dictionary, probably
losing its ordered dictionary behavior in the process but
making it JSON-friendly.
* webob_dicts objects
returns webob_dicts.mixed() dictionary, which is guaranteed
to be JSON-friendly.
