GGPO test branch updated again! We're closing in...

Thanks to diligent feedback from several players* plus tireless testing help from our Linux maven and a certain yung rat, we're on the home stretch...!

• Hopefully COMPLETELY fixed(!) the weird hitches that some people were getting during online play, especially in low-ping matches. They were due to not properly updating what the FPS-throttling code thought when GGPO told the game to wait for the opponent to catch up, before the match started. I TOLD you I didn't know how to write frameskip code!
• Greatly improved the speed of rollbacks by removing a bunch of things it didn't need to do during a rollback.
  
• Improved the L&G/Showtime/KO screens in online play, rollbacks no longer erase them from existence. :^P
  
• Fixed the 49281263778 ping-time bug, now it shows "---".
  

[h3]If you still experience problems, now you can help me find them![/h3]
I've added the Launch option

-ggposhowinfo

which will do a few things:

• It puts a bunch of obnoxious colored text on the screen during online matches any time anything happens with GGPO syncing or other useful info. So only use this for diagnostics. :^)
  
• If you have replays enabled (using -enablereplays), all that text will get SAVED INTO THE REPLAY FILE when the match ends. That way, if there's a match with a problem and you have this option on, you can just post (or send) the replay file and I can look at it.
  
• If you're in an online match and you press Start, it adds a "player pressed Start" message into the log. (Only for the local player, not the online player.) So if something weird happens, please press Start a few times to mark the spot and make it easier for me to find the problem! Please note that a rollback itself does not qualify as "something weird". :^S

"That's enough, for now..."
