Vytautas Šaltenis 461803619b Simplify escapeHTML and uncomment it's benchmark
Simplify and optimize escapeHTML as per @Ambrevar's suggestion: lean on
the fact that we're dealing with bytes: declare a 256-element array with
most of it filled with zeros, except for the few slots that need
escaping. This avoids some conditionals in a tight loop.

Also, uncomment it's benchmark.
