The property didn't hold what it promised in the documentation and
had undesired sideeffects and collided with the fault_tolerant property
when loading PDB files.

So sad to remove our beloved tetris. However, it somehow broke with Python3
and I did not have the nerves to fix it. Any resurection effort is very welcome.

This commit doesn't make OpenStructure work with Python 3. The goal of this
commit was to perform an automated port of the Python code and make it compile.
The performed steps:

- Edited CMakeLists.txt to search for Python with 3.6 as min version 3.6 is the
  Python version shipped by default with Ubuntu 18.04 LTS
- Add version 3.6 to cmake_support/FindPython.cmake
- Adapt setup_boost macro in cmake_support/OST.cmake to prefer versioned
  libraries and not first check for boost_python.so. In the example of
  Ubuntu 18.04, libboost_python.so is specific for Python 2 but
  libboost_python3.so is the one we want.
- apply the following command: 2to3-2.7 -n -w <OST_DIR>
- adapt base/pymod/wrap_base.cc, gui/pymod/wrap_gui.cc and
  gui/pymod/export_message_widget.cc as PyString functionalities do not exist
  anymore in the Python 3 interpreter (replaced by PyUnicode)
- adapt gui/src/python_shell/python_interpreter_worker.hh to resolve issue
  discussed in https://stackoverflow.com/questions/23068700/embedding-python3-in-qt-5
  Long story short: Qt does a typedef for "slots" which causes trouble with
  other headers that are pulled in from the Python interpreter

QT5 shows a widget twice when you set a parent at initialization
and reset the parent later. This is exactly what happens when a
widget is initialized and passed to AddWidget in the gosty app.
The solution is to initialize them without a parent and let
the AddWidget function taking care of it.

IMPORTANT: the harmony example has been removed. If anybody is willing to
invest the required time: go for it...

they are all the same anyway after editing

there are now three startup files; ost_startup.py (former init_cl.py) initializes non-gui ost; dng_startup (former init.py) initializes dng; and gosty_startup initializes gosty (some issues remain what to put into dng_startup as opposed to gosty_startup). also, files are now properly placed into site-packages/ost (on osx and linux)

The Transform class was moved from the mol module to the geom module. A typedef
was put into the mol namespace in C++, and a similar alias was put into the
mol python module, with an added deprecation warning.

move ClashScore to mol.alg, AminoAcid to conop

This finishes changes started in the mem-optimize branch to
remove the AtomProp class from the public interface.
