Allow to sort pages by created_at and title

[igor-drozdov]

Hello,

I would like to propose the changes for sorting pages by created-at and title. It requires files_sorted_by_created_at to be implemented in adapters (I have implemented in the rugged one gollum/rugged_adapter#32).

Please, let me know what do you think about this functionality and the solutions (if you have better ideas for the solution, I am willing to discuss and work on it)

@igor-drozdov Sorry for the slow reply. I think this could be quite a useful addition to gollum. @dometto What do you think?

I'm not against being able to sort pages in various ways, but I am a bit curious what the intended purpose of this is. It adds some complications to the logic of the lib and adapter, and am not sure yet for what reason. Is this to be able to sort in different ways in gollum? In that case, why not just pass a hash with all the info on the files (path, creation date, size) and allow sorting based on that info in the UI?

I am also not sure whence the need for the new public method on Repo in adapter, and the new public method on GitAccess. Wouldn't it make more sense to add the sorting options to Repo#ls_files and keep the rest of the API as is?

Incidentally, this PR should be made against the gollum-5.x branch

Closing for now, please feel free to reopen against 5.x and explain the points I raised above
