## Description of changes
Init of [blenderfarm](https://github.com/LogicReinc…/LogicReinc.BlendFarm)
`blenderfarm` is an "open-source, cross-platform, stand-alone, Network Renderer for Blender".
It can support chunking and rendering of still-images as well as animations over the network.
Due to its architecture it needs some workarounds for the client (which is basically the master and has a GUI) and the server (which is a headless worker).
For the server part this PR implements a nixos systemd service which the client can connect to.
The workarounds are necessary due to `blenderfarm` reading and writing to the directory it is executed from. This can have some undesired sideeffects (such as having renders and setting files in different directories). By adding a custom script `blenderfarm-nix` this is fixed by changing the directory before executing the client.
Also `blenderfarm` wants to download blender on all systems by itself and tries to use this downloaded vanilla version. This obviously doesn't work for nixos. Therefore `blenderfarm-nix` links to blender and installs a version called `nix-blender`. The server systemd service also installs such a `nix-blender` version. By doing so, `blenderfarm` can use this version on the client and server and both are agreeing on this version.
Tested locally on several nixos x86_64-linux machines and VM's.
Still to do: Build and test for darwin.
