Implement Object API

[georgyangelov]

In this branch I put the Object method implementations.

Currently implemented:

• SetAccessorProperty
• GetOwnPropertyAccessor
• GetPropertyAttributes
• DefineOwnProperty
• CreateDataProperty
• GetConstructorName
• InternalFieldCount
• GetInternalField
• SetInternalField
• HasOwnProperty
• HasRealNamedProperty
• HasRealIndexedProperty
• HasRealNamedCallbackProperty
• GetRealNamedPropertyInPrototypeChain
• GetRealNamedProperty
• GetRealNamedPropertyAttributes
• GetRealNamedPropertyAttributesInPrototypeChain
• HasNamedLookupInterceptor
• HasIndexedLookupInterceptor
• SetHiddenValue
• GetHiddenValue
• DeleteHiddenValue
• Clone
• CreationContext
• IsCallable
• CallAsFunction
• CallAsConstructor

Also, I added a few RSpec matchers for a more convenient use of Maybe instances:

• expect(a).to eq_just b <=> a.IsJust && a.FromJust == b
• expect(a).to be_successful <=> a.IsJust && a.FromJust
• expect(a).to strict_eq b <=> if a is Maybe: a.IsJust && a.FromJust.StrictEquals(b); else a.StrictEquals(b)
• expect(a).to v8_eq b <=> same as above but for Equals instead of StrictEquals

I think that's all of them. Should be ready for review :smiley:

Awesome, so excited to review this!

This looks really solid. I'm curious about the dereference issue, but not enough to hold it up!

[georgyangelov]

They shouldn't be needed. Don't really know what I was thinking :)

Actually, I tried removing them, and it was getting confused between the methods that had name keys, and the integer keys, probably because of operator VALUE(). My guess is that VALUE can be constructed from an int32_t and so it doesn't know whether, for the Name object, to convert to VALUE or v8::Local<v8::Name> (just a guess)

I'm trying to tackle exception handling and v8::TryCatch and v8::StackTrace. Any chance you could look at finishing out Template, ObjectTemplate and FunctionTemplate. With those out of the way, we should have everything we need from the C api to get the entire test suite passing again.

I will look at the templates.
