in repository bitbake.

commit bc30d1b235b9ecacef5b2eaa851b9247d857f317

    toaster: orm Add get_base_recipe_file to CustomImageRecipe
    
    This function returns the base recipe file path only if it currently
    exists. This allows us to know whether we can proceed at this point with
    generating a custom image recipe. It also enables us to call this
    function from the templates to enable visual indication of this state.
    
    Some whitespace fixes also added in generate_recipe_file_contents
