// DAVE's BIGASS INGAME JOIN WARNING/DISCLAIMER
//
// Ingame joining is another delicate system. Although not as delicate as server transfer, it will
// help to take as many precautions as possible when handling ingame joins. Please be sure to follow
// all the same rules as explained in multi_strans.h
//
// --------------------------------------------------------------------------------------------------

// --------------------------------------------------------------------------------------------------
// INGAME JOIN DESCRIPTION
//
// 1.) Joiner sends a JOIN packet to the server
// 2.) If the server accepts him, he receives an ACCEPT packet in return
// 3.) The client then moves into the INGAME_SYNC state to begin receiving data from the server
// 4.) The first thing he does on this screen is send his filesig packet to the server. At which 
//     point the server will either let him in or deny him. There are no file transfers ingame.
// 5.) The server calls multi_handle_ingame_joiners() once per frame, through multi_do_frame()
// 6.) After verifiying or kicking the player because of his file signature, the server tells the
//     player to load the mission
// 7.) When the mission is loaded, the server, sends a netgame update to the client
// 8.) Without waiting, the server then begins sending data ship packets to the player
// 9.) Upon confirmation of receiving these packets, the server sends wing data packets
// 10.) Upon completion of this, the server sends respawn point packets
// 11.) Upon completion of this, the server sends a post briefing data block packet containing ship class and 
//      weapon information
// 12.) After this, the server sends a player settings packet (to all players for good measure)
// 13.) At this point, the server sends a jump into mission packet
// 14.) Upon receipt of this packet, the client moves into the ingame ship select state
// 15.) The first thing the client does in this state is load the mission data (textures, etc)
// 16.) The player is presented with a list of ships he can choose from. He selects one and sends
//      an INGAME_SHIP_REQUEST to the server. 
// 17.) The server checks to see if this request is acceptable and sends an INGAME_SHIP_REQUEST back
//      with the appropriate data.
// 18.) If the client received an affirmative, he selects the ship and jumps into the mission, otherwise
//      he removes it from the list and tries for another ship
