Components are pieces of the shell code that can be added/removed at runtime, like extension, but are tied more directly to a session mode. The session polkit agent, the network agent, autorun/automount, are all components, keyring, recorder and telepathy client are all now copmonents. https://bugzilla.gnome.org/show_bug.cgi?id=683156
