[Clam-devel] small web change

[Pau Arumi]

* removed GSoC banner and added a small new one ;)
http://clam.iua.upf.edu/

* all svg sources can be found here to reuse and improve
http://clam.iua.upf.edu/download/misc/

as a side note: anyone is welcome to improve the contents of the
web, the wiki (of course!), and the styles of wiki and planet.
to ease these kind of contributions i've uploaded tarball of the
web also in download/misc. in the future it will be a public svn
like the code.

cheers!
