Improve the Node version warning because why not 

This makes the warning look nice and consistent with the other logs we display, while being safe to never break if a dependency/loaded file is not compatible with this version of Node.
Note that there is some ES6 syntax (`let`, arrow functions, template literals), but The Lounge has not been compatible with Node v0.10 for a very long time now.
