Mid-October update

I am back and I am continuing to review and modify the build process, a few packaging/build related issues should be solved as soon as the next release is out. Due to work-related constraints I cannot give (for now) a solid timeframe, but I hope to have a pre-release in a couple of weeks, maybe a partial one earlier.

The goals are:

• Release a version that contains the new ("experimental") debugger but also ships the "standard" one, that will be - for a hopefully short time - the version to be still normally used
• Release a packaged version for Windows from the new build system (using GitHub actions)
• Include, where possible/desired, versions of GnuCOBOL built with a standard process (also using GitHub actions)
• Release new Linux packages for different distributions (at least Ubuntu 20.04 + 22, Debian 10 + 11, possibly Fedora 35/36) 
• The point above implies using the distribution-provided version of Qt. Since this, on a few distributions, includes Qt 6, the next logical step will be moving the primary target to Qt 6 and leaving Qt 5 - if possible - as a secondary option for older platforms. Obviously this will take some time.
  
  Sorry for the delays but integrating the new debugger into Gix-IDE is/was a long process that needed a break in the development/release, since too many things changed to perform a clean merge between the two versions and maintaining them separate and up-to-date was simply too much work. After the obstacles above are cleared, development should proceed in a quicker way.
