Moving pkgsrc-wip away from SourceForge

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hey,

at pkgsrcCon, we were discussing the state of pkgsrc-wip today. The
consensus of the people in the room was that

a) moving away from sourceforge is a good occasion for moving away from CVS,
b) wip is totally the type of thing that should be on Github.

(b) is evident by the number of people sending in pull requests for
the Joyent mirror of wip. The style in which wip has been developed,
with a very low bar for new contributors each working on a subset of
packages, is a great fit for the github model. In addition, there is
no reason why wip must use the same VCS as pkgsrc or NetBSD.

So let's do this! :) Thomas, what do you think?
