    project.conf: Changed to load plugins as submodules
    
    This commit adds bst_external as a submodule in the plugins/
    directory.
    
    This will allow us to move a bit more freely from
    freedesktop-sdk, which might not always use exactly the
    same version of the set of plugins.
