Add macOS .app creator
mac/makebundle.py Gajim.app to create an .app bundle which can be launched from the desktop on macOS.
It also creates an
.icns icon which is incorporated in the bundle. This requires a tool which is only available on macOS: when run on Linux, no icon is created.
I had to add an 1024x1024 icon for this to look nice.
I am working on a Homebrew formula to automate installation, which is almost done.
