parseNII, use DataView instead of Uint32Array
First attempt to include touch events in XTK head. Current implementation allows scrolling through 2D slices on the left and right side of a 2D renderer.
Further work on touch events. Currently rotate and zoom in 3d as well as slicing in 2d are supported.
Add 2d zooming.

Merge branch 'master' into touch-no-debug
Some experiments with after spinning and other stuff.
Fix compilation for the experimental touch support.
Add escape if added object is not a volume in X.renderer2D.
Reset the original position style for the container of the X.progressbar once the progressbar was destroyed.
More work on touch events. Now supporting zoom, pan, rotate/window-level in 2D and 3D.

Merge branch 'touch-no-debug'
Increase the speed of rotation.
Add shim for ArrayBuffer.prototype.slice since some older platforms don't have it (f.e. Android stock browser < Jelly Bean, iOS5..).
Use classname for testing instead of the instance for compatibility with older browsers.
Don't use the String.fromCharCode.apply(..) calls since they are not supported on older browsers.
