Performance improvements

Reverting a mistake....

One of the changes in 1.1.3 was a mistake so it has been reverted.

The initialisation of the sprite with a zero duration frame sets it up better.

Texture update (re) corrections.

Further improved the way that textures are updated as they were being updated for the wrong frame. Spriter does this very weirdly.
Removed the old fake frame with a zero duration on initialisation.

Improved startAnimation so that any artefacts from a prior animation are removed. This works but it does result in a blink. We really need to add an intelligent morph between animations that caters for sprites moving around in the spriter node hierarchy.

Setting a texture directly was causing a problem with SpriteKit so textures are changed via a SKAction now (seems unnecessary but it works).

Texture changes on frame changes fixed

Fixed an obscure issue where a change of texture on a frame would cause problems when tweening between frames because the tween was still trying to use the previous texture.

Fixed a visual blink.

Solved an old issue where a looping animation with a length that matches or is less than the key time of the final frame would result in a blink each time the animation restarts.

Fixed an important timing bug.
