new LilyDev, 0.2 release

[Federico Bruni]

Hi all

Few days ago I made a new release (version 0.2):
https://github.com/fedelibre/LilyDevOS/releases/tag/v0.2

I chose to keep calling the final images LilyDev, even if the 
repository is called LilyDevOS.
Next week I'll send a patch to update the link in the CG to point to 
this new repository.

I had planned to make also a new release of the old LilyDev (hopefully 
the last one), but I ran out of time. I'll do it next week.


New in this release:

   Added a Debian container, based on stretch.
   Fedora images upgraded to version 27.
   Added all dependencies needed to build LilyPond without any 
warning: extractpdfmark, URW-35 OpenType font files (thanks to 
@karlinhigh for his script).
   GUI apps can now be run from the container out of the box. This is 
based on a couple of assumptions, which should be correct most of the 
times (see the README).
