This required moving the importable less files to a `less-imports`
directory and adding that directory to the less path. Otherwise,
atom.less would import ui-variables from its current directory
(/static/ui-variables) as less searches the current directory before
any other directories on the path.
The settings-view activates the config for each package before it renders
causing the main module to be required in order to call activateConfig().
This was causing serialize to be called when the window state was being
saved which was incorrect since activate hadn't actually been called even
though the main module was required.
