Right now, wad downloading is rather slow. I think it would be a lot nicer if Odamex could download WAD's from any HTTP source.
If true, the client will attempt to open a normal HTTP connection to the URL listed in sv_website + the wad name in question. If found, it will download the file over HTTP. If not, it will then continue on with attempting to download via sv_waddownload like normal. Note that it will not try to reimplement wadseeker by searching for the wad anywhere, merely try the URL in sv_website and if it's not there give up.
Attempt to also find any file with .zip or other archive and extract the wad from the archive.
