Fix issues with building on node 0.11.x by using nan for compatability with older versions
Modified - remove usage of "fast buffer" in pack as on node 0.11.x performance is terrible and on node 0.10.x performance is the same
Use custom functions for v8 object creation, don't use nan when creating objects for 0.10.x and below as with nan it is slower
Merge pull request #17 from dainis/nan_for_0.11.x

Use nan to make it compatible with node 0.11.x
version bump to 0.2.4
return buffer for raw objects
