Change text of requests in request list

On the request page, the column that contains information about the requester has the format:

request x by John Doe

I think it is not interesting at all what the numerical ID of a request is, and can instead use that real estate for more interesting information, e.g.,

John Doe has a question

John Doe wants to sign off

or even:

John Doe has a question
about question x

John Doe wants to sign
off question x

Of course the exact new text is up for debate.
