yaws 1.94

update url/sha1

notes: yaws ships with a default configuration that expects directories to exist at:

/usr/local/Cellar/yaws/1.94/var/log/yaws
/usr/local/Cellar/yaws/1.94/lib/yaws/examples/ebin
/usr/local/Cellar/yaws/1.94/lib/yaws/examples/include

and attempts to host a server on port 80/443

the practical upshot of this is that out of the box yaws will load, throw a warning about the directories above, and die.  supplying them will fail at the ports step because yaws expects to have root level permissions.

tl;dr- should we add a message warning about the above to the caveats part of the script?
