[Ohrrpgce] Upload access on the wiki

[Ralph Versteegen]

Someone (Chalk Flower) just told me that they couldn't upload with the
error saying
"You do not have permission to upload this file for the following reasons:
The action you have requested is limited to users in one of the
groups: Administrator, uploadaccess"

Checking some other users, I see that most aren't in uploadaccess.
Fenrir isn't, but BMR was put in it 2016.

So this appears to be an intentional spam-fighting measure? But I
hardly ever see bots register accounts lately.
