    source-view: disable <Return> accelerator from completion window
    
    I've noticed a problem where completion proposals are getting activated
    when all you want to do is enter a newline. This results in having to
    hit escape a lot just to escape the autocompletion.
    
    Instead, we'll just rely on tab (and accelerators) to complete and make
    Return just add a new line.
