Testing a new implementation of C4Image

Adding C4ImageView to the structure of C4Image… Will also try to
implement new techniques for filtering.
Added new functionality to images

Next steps: add fitlers, rename file to C4Image, merge branch to master
Added new filter methods to NewImage header.

Next step: add missing methods to NewImage.m file.
Added filters to, and updated old filters for NewImage

NewImage can process all iOS Core Image filters except for transitions
and generators. Will add class-level methods for creating images with
generators.
Working on Generator filters...
Added Animations to New Image

I think the class is ready.
Removed old C4Image
Changed NewImage to C4Image

Fixed a couple of errors along the way.
Mega Hacks on NewSlider

Almost ready to transition from NewSlider to C4Slider, replacing
previous implmentation.
Deleted a bunch of files.
Deleted C4Slider
C4Slider transition completed.

C4Slider is now implmented properly, it is a subclass of C4Control,
with a UISlider object linked inside it.
