Remove section about x265 version in Handbrake

[samhutchins]

As of Handbrake 1.0.0 this paragraph is no longer needed

@samhutchins Thanks for the patch! You're right that this section of the "FAQ" should change but that's the wrong wording. You can't delete that entire paragraph or the next paragraph doesn't make sense.

I won't take your patch but I will fix this. Thanks for bringing it to my attention!

@samhutchins Here's how I might re-word that paragraph:

My ratecontrol system couldn't be applied with the x265 encoder in older versions of HandBrake because it didn't allow access to qpmax, critical for maintaining quality in certain situations. The latest version of HandBrake includes a new encoder which fixes that.

... which would leave the next paragraph unchanged.

@samhutchins OK, I checked in that re-worded change. Thanks again!
