//connection notes
//The connection is like http.
//The stream starts with a small header.
//The header is a list of 'key: value' pairs, separated by new lines.
//The header ends with a totally blank line.
//to record an mvd from telnet or somesuch, you would use:
//"QTV\nRAW: 1\n\n"
//VERSION: a list of the different qtv protocols supported. Multiple versions can be specified. The first is assumed to be the preferred version.
//RAW: if non-zero, send only a raw mvd with no additional markup anywhere (for telnet use). Doesn't work with challenge-based auth, so will only be accepted when proxy passwords are not required.
//AUTH: specifies an auth method, the exact specs varies based on the method
// PLAIN: the password is sent as a PASSWORD line
// MD4: the server responds with an "AUTH: MD4\n" line as well as a "CHALLENGE: somerandomchallengestring\n" line, the client sends a new 'initial' request with CHALLENGE: MD4\nRESPONSE: hexbasedmd4checksumhere\n"
// MD5: same as md4
// CCITT: same as md4, but using the CRC stuff common to all quake engines.
// if the supported/allowed auth methods don't match, the connection is silently dropped.
//SOURCE: which stream to play from, DEFAULT is special. Without qualifiers, it's assumed to be a tcp address.
//COMPRESSION: Suggests a compression method (multiple are allowed). You'll get a COMPRESSION response, and compression will begin with the binary data.
//SOURCELIST: Asks for a list of active sources from the proxy.
//DEMOLIST: Asks for a list of available mvd demos.
//Response:
//if using RAW, there will be no header or anything
//Otherwise you'll get a QTVSV %f response (%f being the protocol version being used)
//same structure, terminated by a \n
//AUTH: Server requires auth before proceeding. If you don't support the method the server says, then, urm, the server shouldn't have suggested it.
//CHALLENGE: used with auth
//COMPRESSION: Method of compression used. Compression begins with the raw data after the connection process.
//ASOURCE: names a source
//ADEMO: gives a demo file name
