Automatic block indentation

First of all, good job with the editor, looking quite nice so far!

First thing that I stumbled on when quickly testing it out:

When people type something like... ("|" being cursor)

 function() {|}

When enter is pressed between curly braces for the function content...

function() {
|}

However, after indentation it ends up looking like so...

function() {
    |
}

Thus, it would make sense to automatically insert empty line and indent it when enter is pressed between curly braces.
