XBPS major changes in June 2011.

- A configuration file "xbps-conf.plist" replaces the (un)register target
  in xbps-repo(8) and (un)set-prop in xbps-bin(8). For now, you can set
  the repositories and prefered virtual packages.

- New package pattern matching code from NetBSD. Supports more ways of
  matching patterns in packages.

- Multiple bugs fixed in virtual packages related matching code.
