Subject: i#114206 sd: unshare shape properties for the same type before
 insertion

Regression from commit 9bd99c08e8662becdd5ac8b47ef6f953c14e65fc
(CWS-TOOLING: integrate CWS os128, 2009-06-03), the problem was that the
SvxItemPropertySet was both used to store a property map (information
about UNO properties) and also as a descriptor for a not yet inserted
shape.

The above commit improved performance by sharing a single instance of an
SvxItemPropertySet for the same shape types: this works for the property
map, but doing the same for property values is problematic.

In practice, this eliminates the need for a workaround in oox/, the
user-visible problem was that loading a document with smartart, then
loading a document with group shapes (but without smartart) and saving
it would copy information from the first, closed document (!) to the
second document.

Just removing the oox/ workaround would make

	make -C oox -sr CppunitTest_oox_drawingml CPPUNIT_TEST_NAME="testGroupShapeSmartArt testTdf131082"

fail, unsharing the descriptor piece makes it pass again.
