Added built-in http server

this allows you to get a list of available maps on the server, get the status and download pk3s

pk3 download must get the sv_allowDownload and the download url configured

downloading works when talking to the /pk3 endpoint like this: curl http://localhost:8080/pk3/baseq3/my.pk3
