Problem:
Currently it's not possible to use ExtDirect in the frontend.

Solution:
Add an eId class that provides the necessary methods to use ExtDirect in frontend.

How to Test:

1) Install the attached extension at the bugtracker entry
2) Test the provided Backend module (expected output is an Ext.Msg.Alert-Box and some debug and exception output in the debug console)
3) Add the provided frontend plugin to a page
4) Call the page... You should get again an Ext.Msg.Alert-Box and debug and exception output in your console (e.g. firebug) or directly written into the document as html code
