Packaging: package as GUI app instead of console app

[bitsgalore]

Tried this in setup.py:

https://github.com/KBNLresearch/iromlab/commit/c2ab187fa2ed2513e5bdef0b0cce5933b899b932#diff-2eeaed663bd0d25b7e608891384b7298

But this has the unwanted side-effect that for each subprocess that is started using sub.Popen a console window pops up.

Might need to change Popen calls, see here:

Update to the above: adding shell=True to Popen call seems to do the trick:

p = sub.Popen(args,stdout=sub.PIPE,stderr=sub.PIPE, shell=True)

Popen problem fixed by: https://github.com/KBNLresearch/iromlab/commit/5805416398b93ef0fdd07377ebc1a0339c020dee

BUT:

• After installing as package the executable doesn't run at all
• Strangely executing iromlab.pyw from a console window using pythonw results in the "drive not found" error, even though it runs OK when double-clicking on the .pyw file.

• Non-running executable fixed in: https://github.com/KBNLresearch/iromlab/commit/621812e217ce250497ad96b0a81e62388438d123
• As above, launching the executable from a console window gives the the "drive not found" error. No idea why, but this is not a problem as long as Iromlab is launched from a desktop shortcut
• Iromlab.pyw in source distribution can still be run from command-line by using python instead of pythonw

• The package does not create any start menu items or desktop shortcuts, so these have to be made manually (not really a problem as you only need to do this once). Might be possible to automate this as well though, see:

  http://stackoverflow.com/questions/24841130/how-to-create-a-shortcut-in-startmenu-using-setuptools-windows-installer

  and:

  https://docs.python.org/3.4/distutils/builtdist.html#the-postinstallation-script

  example here:

  https://www.domenkozar.com/2009/09/27/writing-post-installation-script-to-create-shortcut-on-windows-desktop/

  BUT functions to get desktop & write shortcut don't work, so use this:

  http://stackoverflow.com/questions/32154767/is-it-possible-to-create-shortcuts-into-a-specific-directory-in-python

  BUT KB PCs don't use the default Desktop location, so you'd need to get it from the Windows Registry:

All FIXED, Desktop shortcut now created as post-install: https://github.com/KBNLresearch/iromlab/commit/3e798e74aa18d860432c164c905513194a2d7298
