Pool event 'connection' does not match documentation.

[rla]

Code (master) emits connection only, not with error argument:
https://github.com/felixge/node-mysql/blob/master/lib/Pool.js#L51

Readme gives example with error argument:
https://github.com/felixge/node-mysql#pooling-connections

pool.on('connection', function(err, connection) {
  connection.query('SET SESSION auto_increment_increment=1')
});

The behavior you are seeing in the code is correct, it is the documentation that is incorrect and needs to be changed.
