Updated version of Advanced Installer

[lasselindqvist]

Advanced Installer hasn't been updated in a long time. The newest version is v15.9 released on April 23rd, 2019. If needed, I can try to provide a pull request for that.

This repos looks like died. 🤦‍♂️

Totally. I used to maintain this for my last employer and my own convenience, but my current employer doesn't let us easily contribute. If you are willing to become the package owner, you are welcome to start whatever that process looks like.

You are all welcome to make a PR, and I will merge it.
