finger server with cgi-like functionaity

s0.barwen.ch is now running efingerd as a finger server. Rather than display general information about a particular user, it will instead invoke .efingerd in that user’s home directory and return the output. So barwen.ch users can have custom dynamically generated finger information. Note that if you finger from on s0 itself, you’ll get the usual finger information unless you finger user@localhost.
