Title: disable calltips in PySide < 1.0.7 to prevent segfault

PySide bug caused segfault when `QApplication.topLevelAt(pos)` should return `None`, has been fixed in PySide 1.0.7.

We only call this method in the calltip widget (by *far* the biggest cause of crashes in the qtconsole), but if we want to call it anywhere else, we should probably just bump the PySide version dependency to 1.0.7 in external.qt.
