Add comment about own properties

[fhinkel]

Affected core subsystem(s)

JS VM Api

Description of change

Not V8 related, but do we need methods for own properties as well? Also, do we need a method that returns the property without invoking getters and interceptors (similar to v8::GetRealNamedProperty)?

[bnoordhuis]

Engine support may be a bit sketchy. JavaScriptCore to the best of my knowledge doesn't support anything like it and some quick grepping suggests ChakraCore doesn't either.

EDIT: Doesn't mean adding a TODO comment is a bad idea. You have my LGTM if you want it but can you drop the whitespace change?

[mhdawson]

Opening an issue for discussion as an alternative to adding the TODO comment is also an option.

Unless performance critical, this sort of thing is usually accomplished by calling the JavaScript built-in. I.e. Object#hasOwnProperty in this case.

Added issue #67 to track this. Closing this PR.
