		The "dp_clientinfo" command are exported by reunion. The syntax is:
			dp_clientinfo <id>
		where id is slot index (1 to 32)
		After executing this command reunion will set dp_r_protocol and dp_r_id_provider cvars.
		The dp_r_protocol keeps client's protocol
		The dp_r_id_provider cvar will be set to:
			1:  if client's steam id assigned by reunion (player uses no-steam client without emulator)
			2:  if client's steam id assigned by native steam library (or by another soft that emulates this library, server-side revEmu for example)
			3:  if client's steam id assigned by reunion's SteamEmu emulator
			4:  if client's steam id assigned by reunion's revEmu emulator
			5:  if client's steam id assigned by reunion's old revEmu emulator
			6:  if client is HLTV
			7:  if client's steam id assigned by reunion's SC2009 emulator
			8:  if client's steam id assigned by reunion's AVSMP emulator
			9:  if client's steam id assigned by SXEI's *HID userinfo field
			10:  if client's steam id assigned by reunion's revEmu2013 emulator

		If slot is empty, both dp_r_protocol and dp_r_id_provider cvars will be set to 0
		If slot is invalid (id < 1 or  id > max players), both dp_r_protocol and dp_r_id_provider cvars will be set to -1
