Auto indentation and adding of closing braces

[mikeyhew]

The old Rust playground used to auto-indent and add a closing } when you typed { and hit enter. I liked that. Could that feature be added?

There's a bug / ugliness in the version of Ace we are using (1.2.6) around auto-pairing of ', which is super annoying for lifetimes. You can see that the old playground had to work around this behavior. We chose to disable the whole shebang instead (since a previous version didn't have it anyway).

Ace has fixed this in 1.2.7, but the brace package is still on 1.2.6. They would like to upgrade to 1.2.8, but are blocked on a rogue debugger statement added in that release.
