Inreliable releases

[bergentroll]

I am interested to adopt Wyrmsun package from Arch User Repository of Archlinux. I had been surprised that near every release after 4.0 have major build or run errors. With respects, releases are something that you usually expect to be stable and working. CI may help to improve stability. E. g. it seems reasonable for me to build every commit, try to run binary and check exit code. I may help to set up such a pipeline (for GNU/Linux environment at least). I see some AppVeyor notes in Issues, but I can not figure out is it active and for what kind of purpose it is.

If someone would like to contribute an automatic check like that (e.g. making the engine be automatically built with AppVeyor) I would be very grateful. Unfortunately I am only able to build and test the game on Windows right now, so I have to rely on Linux users reporting issues in order to fix them for Linux.

If you have a suggestion on how to solve this issue, I would be happy to hear. I would love to have more stable releases, but I am the game's sole developer, and I can only fix the bugs I find or which are reported (in which I case I seek to fix them as fast as I can).

A way to solve this issue in regards to compilation errors is to use AppVeyor for the repository, of course. A modification of the AppVeyor file for Stratagus could be used:
https://github.com/Wargus/stratagus/blob/master/appveyor.yml

The main differences are that Wyrmgus still uses SDL 1.2, and has some additional dependencies (Boost and Qt 5.14).

In order to improve stability, I've added a test project now (using Boost.Test).

I've added two simple tests, and as more are added, this should help with the stability of future versions.
