Moved from from tar to cp and shell scripting for consistency and correct racing conditions documented in the shell script
Added erlang-base, curl, and ca-certificates
Copied ca-certificates, so Curl functions properly (including internally to freeswitch)
Fixed sound file downloading
Increased the complexity of the default generated password
Merged sudo process, but moved to su-exec from gosu, to clear vulnerabilities
Update Debian distro before freeswitch install, to keep dependencies fully up to date
Updated to the latest Busybox
