Subject: [PATCH] fish: plugins concated to 99plugins.fish

This change allows the entire repo to be imported directly. Some plugins (such
as oh-my-fish's vi-mode) have extra files that are referenced by the plugin
itself. This means we cannot create a generic plugin file structure out of the
plugins that exist currently.
