Yaip is now able to generate simple SSL certificates for a given host.
I don't currently add any extensions to the certificates (such as
alternative names). When I get to testing it with a browser I'll see
what browsers require. However, I think I'll probably generate
certificates for each host, including sub domains, to make life easier
searching.
I've also added a util function to count lines in a file that was used
for testing some of the ssl functions.
