Improve the Node version warning because why not

Browse Source 
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.
