Tweaking `FlxPreloader` and removing now-unessecary Debug logic.
Fixing `FlxPreloader` so that it is 'skipped' when doing HTML5.
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()

FlxTween: avoid potential issues with pooled tweens, closes #951

- made _finish() private and added a public finish() that only works with usePooling == false
- made setDelays(), init(), put() and update() private
- removed ease param from the tween() / setMotion() functions
- init() now only takes a TweenOptions object
FlxGradient: fix memory issues with the overlayGradientOn() functions, closes #928
.travis.yml: also compile for neko
