delete comments in the stream

Allows you to delete your comments directly in the stream, just like any other post. A little improvement upon Mathias's idea.

thank you!!! i had problems with shared posts that shows many many extra menus. but this was caused by my own changes i think... you don't get extra-menu on shared posts?

&& activity.get("verb") == "post") in the if clause works for me

The cause was a misbehaving jQuery selector. I didn't expect that shared posts have a different CSS structure (2 .muted class elements), so I didn't think of testing them separately. Thank you for pointing it out :-)

@digital-dreamer can you rebase this on top of current master? I'd be interested in merging this patch :)
