Version 0.3: a new release after 6years (!)

This is a new release of NetListViewer after

• moving the project from Sourceforge to Github
• modernizing the build system, the required library versions and the Windows installer
• including a new CI for both Linux and Windows

This release comes after v0.2 released back in 2017 (6 years back!) and hopefully will make it easier for any interested user to contribute changes/improvements following a true Open Source collaboration model.

Please open an issue for any compatibility problem with the updated Windows installer, thanks.
