Replaced by types that are more common. This additionally reflects in the
manpages, which should have types the reader is familiar with.

Subject: [PATCH 15/21] 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.

must.
