      Requirement Description

      When we load an external script like
      zk.loadScript('http://ende.de/test.js', 'myscript');

      It might fail to load the external script. In such case, the whole application will halt on Processing message and go timeout with the message:
      Error code 1: ZK error, before mounting. ...

      Although users can see an error message in developer tool. Maybe ZK can check a script's existence before loading.

      Current Workaround

      Check before loading like:

      http://stackoverflow.com/questions/3646914/how-do-i-check-if-file-exists-in-jquery-or-javascript

      Proposed solution

      allow to pass a callback function. ZK calls the callback function after loading is done and pass the loading status no matter succeed or fail.
