Use Nan::To<Type> instead of ->ToType() to
convert caller supplied objects in renderXXX
functions.

Verify that provided options, options.result
and options.result.stats are all valid
objects provided by the caller.
Throw TypeException otherwise.

Introduce low-level tests that invoke
C++ function directly, without additional
JavaScript wrappers.

No need to have EscapableHandleScope, since local
handle is not returned by the method - only
assigned to an objects supplied by the caller.

For bool, double, [u]int32_t there is no need to wrap
a returned value in Nan::New()

https://github.com/nodejs/nan/blob/master/doc/methods.md#api_nan_return_value

The code has been updated to meet
the requirements of the updated V8 engine
as provided by io.js.

In some cases additional EscapableHandleScope
has been provided.

SassValueWrapper<T>::New has been changed:
in case of instance construction via
the function call "sass.types.Color(0,0,0)"
instead of "new sass.types.Color(0,0,0)"
the "new" part is no longer executed by
falling through. This should not be necessary
because the constructor is called by
the NewInstance call anyway.

This fixes the following error:

FATAL ERROR: v8::Object::SetAlignedPointerInInternalField() Internal field out of bounds

Remove unused ctx_w

Some private npm repositiories seem not to carry
custom package.json properties around.
