Module is not "clean URL" setting-aware

Confirmed, imho this is a critical bug, changing priority.

Please test the patch I provide, on my local install it does the trick. Review would be welcomed.

I didn't try that patch, though it has some issues with line endings and it is building the URL manually instead of using the url() function as it probably should be. I've attached an updated patch which uses url() instead.

I also removed the code that strips out the 'en' language code if it's set, as I think that's needed if a user has a language set in their account, to be able to switch back to English.

True, my patch came out kinda messy sorry. I didnt touch much about how the link is being built, that is the original code in the module though.
