=IDProperties bugfix=

Another bug from the tracker, reported by Mike Stramba.
A duplicated Py_XDECREF in the wrong place made assigning
arrays from Vector objects not work.

Also, fixed nasty bug in C API of idproperties (the function
to look up a property from a group was broken).  Fixed a memory
leak too.

In addition, made "del group['property']" delete properties
from group; previously this would just crash (or at least it
should have).  Added a small addition to the example in the
epydocs for IDGroup.
