Updated CHANGES
Removed unnecessary conversion using _to_magnitude.

This is a remnant of the past in which `_to_magnitude` was not used
upon creation.
Store the magnitude when converting to ndarray

When an `__array_` attribute is wanted, it is very likely that was
requested by a NumPy function. We need to convert the magnitude
to an ndarray to obtain the correct, units aware, result.

Previously, the magnitude value was converted to a ndarray and returned,
but the ndarray was not stored in the `_magnitude` attribute.
Very likely, this lead to some unwanted garbage collection.

See #92.

Stop raising AttributeError when wrapping funcs

Before Python 3.2, functools.wraps (used in UnitRegistry.wraps) raised
an AttributeError when wrapping functions without all of the attributes
in functools.WRAPPER_ASSIGNMENTS and functools.WRAPPER_UPDATES. In
Python 3.2, this limitation was removed. This commit removes the
limitation in older versions of Python, as well.

Updated CHANGES
Correct symbol translation for inches and feet

get_symbol('inch') should return 'in' not 'international_inch'.
This seems be a definition error.

This commit provides the updated definition and related test.
