* Add support for x264 and x265 presets
just adds presets for x264 and x265. seems to work fine for me.
* UI tweaks
Make the presets easier to understand, add tooltip explaining preset's effects
* Do things properly, minor typo fix
The macro defined namespaces confused the hell out of lupdate and more or less broke translations permanently. Looks like the only way we can do it is to have a hardcoded namespace, which goes against my instinct, but honestly how likely is it that we'll change the namespace anyway (I guess forks might want to do it, but that's their problem ;) )
