Title: Allow normal sign_up even for invited users (issue #23)

I am new to rails so I am unsure about how to test the code amendments.

You might want to have a look at this logic I just extracted from my application in which I had used the 'devise_invitable' gem.

I am quite sure it will need some corrections in order to actually work from within the gem though.
