Re: New information (success report) for Frescobaldi 3 and the Ubuntu 16.04 repositories

[lists]

I have now finished a run-through of installation instructions. As I have once 
more renamed it the link is now 
https://github.com/wbsoft/frescobaldi/wiki/Installing-Frescobaldi-3-on-Linux-(Package-or-Source)

I'd be glad about feedback:

* confirmation
* questions
* reports about mistakes
* reports about failures
* reports/comments about distributions not covered yet.
