[SDL] New SDL bindings to Common Lisp

[Luke Crook]

There are currently two Common Lisp bindings to SDL listed on
libSDL.org/languages.php. I would like to add a third, 'Lispbuilder'. 

- The project summary page is located at http://lispbuilder.sourceforge.net/

- The Lispbuilder wiki is located at http://www.balooga.com/lispbuilder.php3

The Lispbuilder bindings work in many Lisp implementations across both Linux and
Win32. 

Thanks,
- Luke
