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

added libexec dir to OSX deployment cmake script
fixed path to python library for OSX packaging

Horrible hack (execute_process) to work around the fact that the python modules in Ubuntu are now spread over many directories and symlinked everywhere

Thanks Tobias for diagnosing the problem

fixed lib64/lib detection in copy dependencies script

added skeleton for Linux deployment with CPack

added CPack configuration to create complete bundle dmg on OSX with "make package"

Fixes BZDNG-385

The examples don't really make a lof of sense without
shaders enabled

Closes BZDNG-350

Removed the directories with scripts to create rpm and deb as in the future we will use Andi's cpack

The main advantage of the new script is the ability to also
deploy applications built on OpenStructure, e.g. QMEAN.

It does only minimalistic OST bundles for now, no gui, no
graphics.

Instead of creating a lib/openstructure subdirectory containing
all ost modules, use lib/python$MAJOR.$MINOR/site-packages. This
follows more closely what other projects are doing. The main
motivation, however is to simplify deploment of tools built on
OpenStructure.

The boost.python library gets implictly include with
gosty when buildinga full bundle, but we were
missing it when building a minimal bundle.
