End game button for custom games/being able to surrender at any given time

Hey guys,

A few of you may or may not have been in this situation; You went into a custom game to record something for a video or you just want to test something out. But after the recording/testing is over, someone stays in the custom game. May it be because he didn't understand he had to quit the game afterwards or he just wants to destroy the enemy nexus. While the other player is still in the custom you can't start a new game in the meanwhile and sometimes I had to wait even 20 minutes before I could start a new game because of this.

SO, my idea was to implement a button that forces the end of the game. Since this button should only be implemented in customs (in my opinion) you can't really do anything wrong with it I believe.

To summarize it: When you are done testing/recording in a custom game, you can press the 'END GAME' button and the game stops. No team wins. The game is just over, and you can move on to your next game without having to wait x minutes.

Note: Some of you might say, just call them on skype/teamspeak/... and tell them to leave. But not everyone might have teamspeak and if you're playing with some randoms you might not want to give out your skype username.

**EDIT:

After discussion with some friends, we've come to the conclusion that being able to surrender at any given time might be a better idea to prevent abuse of the end game button, yet still serving the same purpose!
