Pipe output directly to str and avoid additional memory allocations
Currently, there are lots of examples of code like this, ``` str << ('<tag ' << foo << ' ' << bar << '/>') ``` which create the string for the tag in memory before piping to str. We can avoid creating all of these intermediate strings by dropping the paranthesis and piping directly to str. This relies on the `str` passed around to handle lots of small appends. This is a problem when using RubyZip, but that is solved in the next commit.
