- Allow registration of V8 extensions with no native function handler (issue #433).

- Add a CefV8Context::InContext() method to test if V8 is currently in a context (issue #427).
- Verify that a current context exists when creating V8 arrays, functions and objects (issue #427).
- Add a v8::HandleScope in GetCurrentContext() and GetEnteredContext() to avoid "Cannot create a handle without a HandleScope" V8 errors (issue #427).
