Slight bootstrap re-organization

[Brian Rice]

I've updated this again, so that post-bootstrap.slate calls a method  
"start" on lobby which prelude.slate defines as "REPL start". This is  
obviously adjustable, so that, e.g. the SDL UI or a socket server  
could be started instead.

Alpha images and the tarball have been updated to this setup, and  
will break if the relevant patch isn't pulled.

Also, the core images are now down to 607kb in size due to separating  
out further libraries. The default slate.image is up to 3.5mb,  
however, but adjusting prelude.slate can change that drastically.
