Convert EHI to TEXT

As far as we are aware, the only ehi file type we know of (HTTP Injector configuration) is text based, so you do not need to convert it to a text file (ehi to text conversion), because you can already open and edit it using any text editor regardless of its actual extension. Should you really need it, you can always rename the suffix from ehi to txt or similar text suffix so it is automatically associated with text editors.
