Doing the "using namespace" penance by adding in v8:: everywhere, like I should have to begin with.

Also:
  - SkWindow now has createSurface, not createCanvas.
  - Add the platform init code v8 now seems to require.
  - Fix library linkage.
  - Call isolate->Enter(); because it doesn't look
    like v8 starts with a default isolate to begin with.
