Add QT_VERSION_STR define to OpenShotVersion.h

Browse Source 
The CMake process will pick up Qt's Qt5Core_VERSION_STRING and
stick it in a cache variable (with forced updating each run),
and a new `#define` in the header exports it to the library and
to the Python bindings so that it can be queried at runtime.
