Prefetch mode of operation

[n8gray@…]

As a laptop user I have intermittant network connectivity. It would be very useful if I could fetch all the sources needed for building a port and its uninstalled dependencies *before* building anything. One way to do this would be with a 'recursive' flag to 'port fetch'. Another (better, IMHO) option would be to allow 'fetch-first' as a permanent mode of operation. I would prefer to work this way all the time anyway.
