Minecraft 1.7 will allow minigames to reset, and some other small chat additions

UntitledMinecraft 1.7 certainly has some huge changes and additions, as shown from Thursday's giant snapshot. But what about smaller features? Dinnerbone posted the above snippet of code on GitHub today, which is also conviently posted below:
/sayraw {"text":"Want to reset the current minigame? ", "extra": [{"text":"Click here!", "clickEvent":{"action":"run_command", "value":"/scoreboard players set minigame_resetting 1"}}]}

{
"text": "Want to reset the current minigame? ",
"extra": [
{
"text": "Click here!",
"clickEvent": {
"action": "run_command",
"value": "/scoreboard players set minigame_resetting 1"
}
}
]
}

But what is it? Well, it's code to reset minigames (and their scores) built into the game. This will be a great help to map creators as a way to quickly change or stop minigames, which should allow for more efficient maps. Dinnerbone also tweeted, "There are other actions, like open a url. Screenshot links are clickable now, also."

Even though this is a very small change (and not very news-worthy) it is still a great improvement that will be coming in the next snapshot, and eventually, Minecraft 1.7.
