Changes to build file

[Kevin O'Neill <ke...@rocketred.com>]

I had some problems building slide from scratch. The instructions contained 
in the README file seem to be a little out of date.

So I've modified the build program to, in my opinion :), make it easier to 
get "up and building" with slide.

The major difference is that I symlink the dependent libraries into the lib 
directory. My modified build.sh adds each jar file in the lib directory to 
the classpath before launching ant. To enable or disable a feature is just a 
matter of adding or removing a link.

If this is an acceptable approach then I'll update the README and submit the 
diffs to this list. Of course this doesn't really help those on the wintel 
platform, but that's a problem for another day.

Regards,

k.
