Explore package testing possibilities & push auto updates on commit

[theChaosCoder]

One idea is to check if a commited update / new package is valid and then auto push a new compiled avspackages.json. Makes more sense if more people will commit something.

That means it has to be checked whether

• avspackages.json can be compiled without errors
• the latest commit can be "installed" ( hash + url must be valid)
