Add convenience getter for Local from Persistent

[kkoopa]

This is found in newer versions of V8. Needs checking that no leaks were introduced.

Pretty big set of changes, I won't have time to review and am probably not the best for this one anyway, maybe @bnoordhuis or @agnat if they have time.

Missing docs though, is it just Get() that we want to add or should more of this be officially documented, (like .persistent?)

[kkoopa]

Just Get, the rest is private, so no point in documenting anything else, since it is not accessible. There were many changes, since I redid the newer implementation not to inherit from v8::PeristentBase<> but to compose it.

I wonder if we can simply add Get to Nan::Persistent and Nan::Global instead? This would preserve Nan::PersistentBase and its subclasses as subclasses of v8::PersistentBase FWIW.

Yes, that would work, but I wanted to try and redo the implementation to make
it more similar to the other one. Now the hierarchy is the same across
versions, as would be expected.

Sounds reasonable to me. There is an assumption that the user would never need access to the v8::PersistentBase object, hope this will remain true.

[kkoopa]

That assumption is already there for versions less than 0.12, this makes it
explicit in newer versions too. v8::PersistentBase cannot even be directly
instantiated.
