Added missing browser package.
Fixed Build script and auto/config.

Fixed major bug in auto/config, missing symlink for debootstrap, which would halt build.
Also updated build script to correctly notice if squid was already running.
Build defaults to squid3 if installed, as regular squid does not support IPv6 addressing.
