This tool now only supports installing packages, it won't build any
dependency anymore. This implies that on most distributions, it wont
make a complete Blender build possible, some features will likely be
misisng.
By default, it only install basic dev environment to enable building
Blender with the precompiled libraries (which is the recommended way).
Passing the `--all` option will make it try to install all known
dependencies from distro packages. This is a development option,
regular Blender build should be done with the precompiled libraries.
Tested on Debian Testing, Arch, Fedora and Suse Tumbleweed.
With the new design, it should be fairly trivial to add more
distributions if desired, and maintenance should also be way simpler.
NOTE: side effect is that a working python3 interpreter is expected on
system running this script. In practice this should not be an issue,
since Python3 is installed by default in almost all regular desktop
linux installations.
