Ek comments

* Add accept match request button to match request show page
* Add controller action to accept match request
* Match Request show page shows "confirmed" if confirmed and am "accept" button if not confirmed
I'm not exactly sure how I could put it in a partial because when I make a new comment on the match_request show page, I have to pass along a hidden field. When I'm editing it, the route is comments/:id/edit so I don't need the hidden field anymore. I'd love to be able to put it in a partial though.
