[PATCH] Erlang: Use single quotes in argument to code:lib_dir(Name)

[Richard Carlsson]

Name should be an atom (single quotes), not a string (double quotes). The

current code works by accident, but could stop doing so in future releases

of Erlang/OTP. See http://erlang.org/doc/man/code.html#lib_dir-1
