What is left of the SkView system is used only by samples or viewer. As a result, move it out of the Skia source tree and re-organize so it is a bit easier to understand and use more shared code. Move samplecode/ClockFaceView.cpp to samplecode/SampleTextEffects.cpp, sice that's what's actually in it. Move SkAnimTimer.h to tools/timer, since it's actually shared between gm and samples.
