VPN profiles for Cisco AnyConnect

Populate some commonly used VPN profiles for Cisco AnyConnect. These
hostnames should not be considered confidential - they are available on the
Internet, proactively monitored, and offer nothing without a valid login.

It seems that AnyConnect doesn't really respect HUP signals. So you'll have
to re-launch it yourself.
[dcarley] Include VPN profiles.
