Explain better in Welcome dialog why Orwall is not a firewall

[ghostlands]

...because it sure sounds exactly like a firewall. Allow and/or prevent leaks? This is what a firewall does, right? Is the issue that it is exclusively an outgoing firewall?

Honestly the assertion that it can't substitute for Droidwall doesn't make a lot of sense on an intuitive level. Better wording or a slightly more detailed explanation might be nice.

Perhaps say that Orwall cannot control incoming connections, only outgoing ones, and thus is not a complete firewall solution? Maybe "complete" is the missing word here.
