Title: Check global vitality variable

For some reason checking just `loaded_vitality` in the script doesn't work. I've also looked at the vitality code and don't see why. To prove this you can add `echom exists('loaded_vitality')` anywhere and see that it doesn't return true while `echom exists('g:loaded_vitality')` does.
