Add finger demo to redbean and fix regression

Browse source 
This change fixes a regression in unix.connect() caused by the recent
addition of UNIX domain sockets. The BSD finger command has been added
to third_party for fun and profit. A new demo has been added to redbean
showing how a protocol as simple as finger can be implemented.
