Ruby 1.8 implementation. Respects Rack specs.

Public Instance headers=(key_value_pairs)
Ruby 1.9 doesn‘t have a String#each anymore. Rack spec doesn‘t take care of that yet, for now we just use each but fallback to each_line on strings. I wish we could remove that condition. To be reviewed when a new Rack spec comes out.
