migrate vxl homepage to github

The http://vxl.sourceforge.net homepage is out of date and only a few people have access to update it (I'm one of them). I propose that we migrate the VXL homepage to vxl.github.io by adding an appropriate GitHub Pages repository.

I've created the vxl.github.io repository and populated it with the same history as the original sf www repo (which can be cloned via this url.

Now the homepage content can be seen at https://vxl.github.io/.

It does need some updates.

@hjmjohnson if you agree with this approach I can update the old site to just point to the new URL.

[hjmjohnson]

@bradking This is GREAT! Please do have the old site simply point to this new site.

@bradking I'll make a pass over the web page in the next month (after classes end in 2 weeks) to update the content.

[bradking]

@hjmjohnson great. I've put the redirects in place from the original URLs.

@bradking overdue, but Thanks for this effort of continuing to move vxl from sourceforge to github.
