Set a homepage for the module.

It seems like roughly release time.

Fix typos in afs.acl and afs.fs introduced in 0e2974f1.

Add a krbname property to afs.pts.PTEntry, which converts the
PTEntry's name to a Kerberos-style principal.

Add afs.pts.PTS.getEntryFromKrbname, which converts a Kerberos

Merge branch 'pts-orm'

First attempt at an ORM-like interface to the PRDB.

Missing features that should eventually be added:
 - Create/delete users/groups

 - Expose afs._pts.PTS._AfsToKrb5 and afs._pts.PTS._Krb5ToAfs.

   _Krb5ToAfs could be exposed as a method to return a PTEntry from a
   Kerberos principal, while _AfsToKrb5 could be a method (or
   property) of a PTEntry that returns the equivalent Kerberos
   principal.

Implement the ability to set ACLs.
- Added pioctl_write and setAcl to the Pyrex code

  apply the ACL.  ACLs set to 0 are pruned before applying.
