New Cesium packaging via makZipFile changes

1. The original zip file is still created, but now known as Cesium-amd-<version>.zip
2. A second zip file is also created, Cesium-<version>.zip.  This new zip contains only the minified Cesium, Assets, Documentation, and a new skeleton.
3. The new skeleton doesn't require a build process and simply creates the 3 main widgets on an empty globe (though we can change this).
Merge branch 'master' into packaging
Forgot to rename old zip file.
Move skeleton.html build logic into `combine` target.
Simplify skeleton and rename it to HelloWorld.
Merge remote-tracking branch 'origin/master' into packaging
Fixes from my last commit.
Simplify fileset.
Rename larger zip package to Cesium-full-<version>
Change SVG colors to not use RGBA (technically not allowed).
Standardize CSS names

So far, our widgets have been playing fast and loose with the CSS
namespace.  This standardizes everything to avoid potential
collisions.  The new rule is everything should follow the
cesium-<item>-<cssClassName> convention.

Examples:
cesium-lighter
cesium-widget-[xxx]
cesium-timeline-[xxx]
cesium-animation-[xxx]
cesium-fullscreen-[xxx]

I'll also update the coding conventions once this is in.
