Update PyQt4 to 4.11.4, SIP to 4.17 and QScintilla2 to 2.9.1.

Bring in some long overdue updates, some of which are required for us to
later land the PyQt5 ports.

One big change with this update is that the PyQt4 ports now install their
.sip files into share/py-sip/PyQt4 instead of share/py-sip. This way we do
not end up with directories like share/py-sip/QtCore, which are especially
confusing once PyQt5 lands and starts installing files with the same names.

Other noteworthy items:
- PORTREVISION has been bumped on ports depending on devel/qscintilla2
  because libqscintilla2.so's SOVERSION has changed.
- graphics/seexpr has been converted to USE_PYQT, as the file it used to
  define a build-time dependency on x11-toolkits/py-qt4-gui has moved.

Once again, big thanks to Tobias Berner <tcberner@gmail.com> and Guido Falsi
(madpilot@) for their initial work on these ports as part of the effort to
land PyQt5 into the tree (see D2910 in Phabricator for an earlier version of
the PyQt5 patch set).

- Detect eigen2 by checking for .pc file, not min. port version.

If a user had eigen3 installed, but not eigen2, the min. port version
check would not differentiate between the two.

Add openscad.
OpenSCAD is a software for creating 3D CAD objects.

Unlike most free software for creating 3D models, it does not focus on
the artistic aspects of 3D modelling but instead on the CAD aspects.
Thus it is more suitable for creating 3D models of machine parts but
perhaps not when creating computer-animated movies.

OpenSCAD is not an interactive modeller. Instead it is something like
a 3D-compiler that reads in a script file that describes the object
and renders the 3D model from this script file. This gives designers
full control over the modelling process and enables them to easily
change any step in the modelling process or make designes that are
defined by configurable parameters.
