vim: Explicitly ignore .git & node_modules in CtrlP
vim: Explicitly ignore .git & node_modules in CtrlP

I've been increasingly seeing `.git/*` and `node_modules` files show up in the
CtrlP file list, despite using `ag` and having them agignored (w/ .git files
being ignored by default).

For right now, simplest solution is to just explicitly add them to ignore list.
