Rename all the things

Rename all the things

This CL moves the bulk of the SkyView code out of the |framework| directory
because the |framework| directory was redundant in Dart package import
declarations.

RSLGTM. As per our discussion, a follow-up CL (not necessarily from you) should
split app/view and app/scheduler into two different directories (app/view
depends on rendering/, but app/scheduler is a peer to painting/ in the layer
cake); and should fork ./framework/animation/, ./framework/debug/ and
./framework/net/ into ./*, so that when we're done with the old webview world we
can nuke all of framework/* at once.
