create a gyp file

[booo]

The build system is going to change in the new node version. We should add a xyz.gpy file to the project.

Good starting point is: https://github.com/TooTallNate/node-gyp

but it does not work yet:

$ node-gyp configure build                                                                                                                                system master@55a6f2e ✗
gyp info it worked if it ends with ok
gyp info using node-gyp@0.5.7
gyp info using node@0.8.1
gyp info spawn python

ok this 9291ca9d1795f17ef7d5ef2127734f031df2146d should fix the compile error on os x.
