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.
