Add ID to module view

Based on a request in the mailing list which originated from the forums:
https://groups.google.com/d/msg/joomla-dev-cms/fRvI7qsedbU/VwJLzslLLIUJ

### What this does
This PR adds the module ID to the module edit view.

### Testing Instructions
Apply patch and see if the ID is now shown below the "note" field.

As for the position, if you have a better idea as to where to show it, I'm open :smile:
