limit all users to 250 projects by default

Rough envelope math reasoning here:

  - 100k sure does seem like a pretty massive default.
  - On a quick sampling of long-time users of various code forges, people
    tend to have < 150 repos.
  - Pad out with an extra 100 on the theory people might fork a whole
    lot of extensions etc.

This can of course be revisited.
