Allow users to choose if they want to put BornAgain in the path or not on Windows
|Status:||Backlog||Start date:||03 Apr 2019|
Currently windows installer puts BornAgain in the python path.
It is not always desirable, since some of the users may want to have several distributions at once.
Therefore it is desirable to add an additional frame in the dialog with
a check box allowing to select if BornAgain should be put into the python path.
