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.

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.
