Make keys follow Vim's mapping

[Ileca]

Using an azerty keyboard, I remapped all the numbers to be like qwerty. However, it doesn't work with Startify that follows original keyboard mapping of numbers. I think it would be better if Startify would follow user's own mappings instead of having its own, as it forces you to remember two sets of keys. Maybe an option to deactivate that if people prefer the original behavior.
