Status in Physical Quantities for Python: Fix Committed

Bug description:
Quantities does not handle absolute temperature scales; instead, temperatures are assumed to be temperature differences. For example

>>> T = 20 * pq.degC
>>> print T.rescale('K')
20.0 K

This behavior, is noted in the Quick-start Tutorial, but since it will be a common misunderstanding, should be given more emphasis.
