Completely revamp installation script

Browse source 
Instead of cluttering the $PREFIX during build (and requiring root to do so),
we now install everything into a temporary directrory that is copied in piecemeal
to the prefix). Additionally, the installer will now, on a fresh installation only,
copy the base config files from /conf to $PREFIX/etc/nginx. A existing installation
will not have this performed (unlike the upstream nginx installation rules), so your
configuration will be safe.
