Pull #14

travis-ci

allows using `app.listen` instead of `app.server.listen`

`app.listen` is re-mapped to `app.server.listen` (only if `app.server` was created here)

For advanced user (if `app.server` already existed), it is assumed that they will manually call `app.server.listen()`. But if they're still calling `app.listen`, it'll wait for `app.server.on('listening')` which if it doesn't occur in 100ms, it shows a warning that IO will only work if `app.server` actually starts listening.
