Foobar2000

We will start the portability with version 1.4 as the first step - the other Foobar project was stopped in 2011.
The second step (or parallel project) will be create the portability for plugin MP3tag (https://www.mp3tag.de/en/fb2k.html) that will work with MP3Tag portable (https://portableapps.com/node/18890) - note is not necessary to make the portability for this one, you can to extract EXE to a USB driver, it works.
