 I was playing with a profiler this afternoon, and was surprised to see
 that '''10%''' of the request execution time was being spent on ent2ncr().
 That's incredibly high.

 The patch I'm about to attach replaces the 250+ str_replace() calls with a
 single one, which seems to be around 5-30x faster in real-world
 situations. The speed difference decreases as the length of text parsed
 increases. It was just a bit ahead at ~40,000 words of text, and the
 profiler choked on anything more.
