Documentation misleads embedders

[Silur]

The most recent documentations still claim that one can make nodeJS addons in C: Node.js Addons are dynamically-linked shared objects, written in C or C++
However currently there is no official way for this to happen using pure C, only wrapper-hacking and thirdparty tools. Either stop lying in the docs or provide a source where one don't have to use namaspaces and C++-only data types to write a node extension.
