Extended LOCAL_NETWORK to support comma seperated list of /CIDR.

Minor firewall cleanups. Removed specified TCP in range allow. No point, we don't specify tcp/udp anywhere else.

Formatting changes (BASH 3+ style).

Cleaned removed external [ ] calls. Use builtin [[ ]].

Use ${VAR,,} to lowercase isntead of TR.

Added OPENVPN_OPTS example.

UFW_EXTRA_PORTS Allows for exposing of ports when binding to the image for the vpn functionality. Accepts comma seperated list.

Changed from /bin/sh to /bin/bash. If you got bash, why use busybox? Plus busybox doesn't allow for advanced string manipulations.

Added python2.7 and pysqlite2. torrentToMedia from the nzbToMedia package needs python2.7.
