[libpeas] Added a plugin-list property to PeasEngine

[Steve Frécinaux <sfre src gnome org>]

commit 616e8f4a726c37c00a808ef75d5289ec6a874b94

    Added a plugin-list property to PeasEngine
    
    With this new property the engine users will be able to track changes
    in the available plugins list, so for instance the plugin manager can
    stay up to date across calls of peas_engine_rescan_plugins().
