v0.5.0

Bugs
 * fixes supervisor dangling processes (thanks @oXis)
 * doxyproxy container name cant have slashes
 * wrong port displayed on doxyproxy start message when using configured
   port

Enhancements
  * Configurable port for doxyproxy (thanks @oXis)
  * Now works without `privileged=true`
  * Added support for WSL2
  * Docker daemons that run in VMs (windows/macos): use special hostname
    for haproxy that points to the VM IP running the daemon.
    `network=host` doesn't work on those environments
  * Fewer default threads
