Upgrade packaging to node-gyp

[ghost]

I have tried to upgrade so that this addon builds for windows using the updated packaging mechanisms but have failed miserably.

I think it would be great if this addon used the latest packing so that I could make a decent attetmpt at a windows build.

My attempt thus far fails wit the following error:

LINK : fatal error LNK1181: cannot open input file 'occi.obj' [C:\repo\node-db-oracle\build\binding.vcxproj]

Thats just fyi.

I know several people who would love to use this module if it would work on windows. It would be awesome if you could convert the wscript file to a binding.gyp file (http://code.google.com/p/gyp/wiki/GypUserDocumentation)
