Jeff Schwab e609d83f1a Fixed an incompatibility with Ruby 1.9.
Ruby 1.8 strings are Enumerable, but there is no String#lines method. In
Ruby 1.9, the situation is reversed.  To work around this disparity, the
RailsEnvironment#externals method now explicitly checks whether a String
responds_to? :lines.
