Element text item with are now converted to dynamic element text item.

From now, the class ElementTextItem is not anymore use in qet. Every texts in a diagram are DynamicElementTextItem. the Xref item was adapted to dynamic text. Previously, the comment and location, displayed as a "static text" below the "old text" tagged "label" are now automaticaly converted to DynamicElementTextItem, so visually, these texts stay unchanged git-svn-id: svn+ssh://svn.tuxfamily.org/svnroot/qet/qet/trunk@5216 bfdf4180-ca20-0410-9c96-a3a8aa849046
