Created shortcut do not work on macos (at least)

[t20100]

Running dioptas makeshortcut on macos creates a shortcut on the desktop that is not working. This is because this call /path/to/env/bin/python /path/to/env/bin/dioptas.py but there is no dioptas.py available. I expect it to be the same at least on linux.

The make shortcut option has been created by @newville. If I am not mistaken, he has also now created an extra library, to do this.

@CPrescher I'll investigate....

Thank you. I guess the main issue is that "dioptas.py" in the main directory was renamed into "run.py" due to some problems I had with pyinstaller (if I remember correctly MacOSX cannot distinguish files from folder with the same name)
