Windows: Broken node alias

The node compatibility link is unusable on windows. Addons depend on doing a callback to the specified executable module via node_module_register, which is not possible when the name is wrong.

If an addon depends on iojs.exe, it cannot be used through node.exe and vice versa, giving the 'Module did not self-register.' error.

node -e "require('./test/build/Release/addon')"
Error: Module did not self-register.

iojs -e "require('./test/build/Release/addon')"
