Semi-automatic update. These checks were done:
- built on NixOS
- Warning: no binary found that responded to help or version flags. (This warning appears even if the package isn't expected to have binaries.)
- found 1.4.15 with grep in /nix/store/7nifpbj16dlhljb2jwbwxyv4wx1zwa1y-mosquitto-1.4.15
- found 1.4.15 in filename of file in /nix/store/7nifpbj16dlhljb2jwbwxyv4wx1zwa1y-mosquitto-1.4.15
as of now it is just built and copied to the right place so that
the server can be run. hopefully i will be tweaking with the
configuration files in the future and tweak this a bit more
