log_help: Fix mem leaks

Browse source 
`_content` vector owns elements so that when the `ContentListing` is deleted so is the content.
Remove `get_content()` method in favour of `begin()` and `end()` const iterators.
More `const` in general, and iterations over `ContentListing` use `&content` to avoid copying data.
