Feature Request: allow import of skipped/hidden files

[cyberwombat]

I have large libraries that I place under a vendor directory and I would like to not see them in my window or go through the hassle of telling codekit to ignore them. But if I add 'vendor' to skipped items in preferences then codekit will no longer import them into other files even if explicitly add them such as @codekit-prepend "../vendor/spinner/spinner.js";

:+1: +1 on this. I recently started to separate out my 3rd party assets using bower and found this to be an issue.
