Subject: Create necessary directories, add 'local =' parameter

Ensures stunnel can actually be used after installation.
Add optional 'local =' parameter to a tunnel, to force binding to a particular IP for outgoing connections. Useful for transport mode IPSec, or with VPNs in general.
Known issues: After (re)install, list of tunnels must be saved once to produce proper config file. Not sure why this isn't happening automagically.
