Add rdoc to gem dependencies for the sake of Ruby 1.9.2

Without this, attempting to run rake in 1.9.2 will raise a confusing
error message about changing 'rake/rdoctask' to 'rdoc/task' in Rakefile,

Have Travis check Ruby 1.9.2
remove warning about unused variable and actually set message

cleanup trailing whitespace
