Initial commit of the autobrace KTextEditor extension.
Inserts a closing brace on pressing Enter when your current line ends on an opening brace ("{").

Example:

void blah() {
if (foo) {<cursor>
}

On pressing Enter, this gets you:

void blah() {
if (foo) {
<cursor>
}
}

The new line with <cursor> is indented according to current indent script, the autobrace extension has no influence on that.
