nan 1.0.0 alignment

[fivdi]

A number of things need to be adjusted when nan 1.0.0 is released.

---

NanAssignPersistent has two parameters rather than three, the first is no longer required, so

NanAssignPersistent(v8::FunctionTemplate, constructor, ctor);

becomes

NanAssignPersistent(constructor, ctor);

---

There's now a NanNew function template and template specializations for creating new v8 objects. See also NanUndefined, NanNull, NanTrue, and NanFalse. They hide the isolate dependencies. For example

v8::FunctionTemplate::New(Epoll::New)

becomes

NanNew<v8::FunctionTemplate>(Epoll::New)

---

NanNewLocal has been removed and NanNew should be used as a replacement, so if NanNull is also used

NanNewLocal<v8::Value>(v8::Null())

becomes

NanNew(NanNull())

---

Are any other alignments required?
