> Typical string that need to be unescaped contains almost no XML entities, so copying
input string to output buffer char by char is slow.
> I've refactored Entities.unescape() so it works faster. Going to submitting patch and
tests.
> Patch contains both hacked and original versions of unescape, to run tests.
> Test shows that performance remains same on short strings, and much better or large strings
with rare entities.
