Ann: Primary git repository moved

Hi,

The primary git repository has been moved from www.swi-prolog.org to 
github.com.  That means that developers need to push to the github
repository.  The repos at www.swi-prolog.org are synchronized three
times per day.  What does this mean?

# Update an existing working tree to GitHub

Use the commands below to update a working tree for the development branch.
Use `swipl.git` for the stable series.  If you have a GitHub account and 
setup
ssh, you can also use `[email protected]:SWI-Prolog/swipl-devel.git`.

     % git remote --set-url origin 
https://github.com/SWI-Prolog/swipl-devel.git
     % git submodule sync

# Checkout old versions

The submodule locations have changed on April 22, 2014.  If you want to
check out an older version, use the repositories at www.swi-prolog.org.
You can use the above commands to switch freely between both sources or
use `git remote add` to add both of them.

	Enjoy --- Jan
