Adapt to nan 2

[gagern]

In libxmljs/libxmljs#330 libxmljs migrated to Nan 2, and in gagern/libxmljs@f6c2c2f libxmljs-mt followed suite. This is causing some build problems, as quite a number of Nan names have changed. I wonder whether it is safe to use Nan 1 and 2 in the same library, but probably wouldn't risk it. Instead I suggest node-libxslt be moved to Nan 2 as well. There is some 1to2.js script hidden in the Nan directory tree, but so far I had found that thing caused more problems than it addressed.

I just tried the 1to2.js tool and get a bunch of errors.

I am not in a very brave mood, I guess I will wait for the migration guide: nodejs/nan#402

Adding to the list: nodejs/node#2798.

https://nodesource.com/blog/cpp-addons-for-nodejs-v4 appears to be the official migration guide, suggesting upgrade-utils to automate large parts of the migration process. Haven't tried this yet. If someone wants to give this a shot, please do.

I made a stab at this, see #26. Users are welcome to try with various node versions and with real life applications. I make no guarantees at all.

@albanm please bump the version of module with nan 2 to install it from npm.

Hello,

Sorry for not being very present. I am not in a good situation to work at home.

We had already talked about it, I just added you as contributor to this project and owner of the package on npm. Feel free to do what is necessary, I will catch up later.
