Tweaking `FlxPreloader` and removing now-unessecary Debug logic.
Fixing `FlxPreloader` so that it is 'skipped' when doing HTML5.
Improved how FlxSprites can be made flippable

Replaced "flippedWidth > 0" with "flippable"
Removed flippedWidth
Removed SfxFader and Fader

- fader tweens FlxG.sound.volume, a regular tween works just fine for that
- SfxFader tweens the  volume of FlxSounds, which already have fadeIn() and fadeOut() functions
FlxSound: small optimization for fadeIn() and fadeOut()
FlxTween: add default values for duration
FlxPoint: added subtract() and subtractPoint()
