Subject: [PATCH] Fixing SRTP Feature on Default Settings Value Dial_String

1-It properly fixs SRTP feature on TLS enabled environment. It includes new dial_string value on /app/extension/app_config.php and then autogenerated /etc/fusionpbx/config.lua file would be created with properly dial_string values too on installation process (scripts.php).
2-It also solves issue when Endpoint register with uppercase "TLS" protocol instead lowercase "tls". Regex is case sensitive,rtp_secure_media variable would never turn true with TLS Contact uppercase cases!
3- It still accepts transport in lowercase "tls" transport ambient.
4- Now, every outbound INVITE to a TLS or tls endpoint Contact would receive crypto options inside SDP messages. Endpoints with compulsory SRTP feature enable should work ok now.
