Support base committer category for security

[jberry@…]

We need to restrict commits such that:

Any commiter can change:

trunk/dports

Only "base" committers can change:

• trunk/(all other)
• downloads/
• tags/
• branches/

I'm not sure what the full set of base committers should be now, as we've certainly lost some, but for a start:

jmpp, mww, jberry, pguyot, yeled, kvv, landonf, jkh, ...?

At some point, we may need to provide access to www or docs for a broader set of users, but it's not clear to me at present that's necessary given our new documenation arrangements.

Stealing kvv's tickets... I'll do some research on the options for this.

Email me a map of directories to lists of users and I'll implement this. I dont need the list of committers, you can just call them "committers". For admin, base, whatever-else, I'll need a list (of email addresses registered as MacOSForge).
