Suport for image files and ignore directories

[paulodiovani]

Previous, any image file was simply not being served, as Raneto tries to parse it as markdown.

This Patch adds a simple test before serving a document and, if it's a simple image file, just serve if with sendfile().

[gilbitron]

It's a nice solution but I'd rather see people use public/images for serving images and maybe add a %images_url% variable that can be used in Markdown files.

[paulodiovani]

But using public/images/ will forbid relative paths between Markdown files and images (or download links).

Figure that someone may want to be able to read his documents on GitHub as well. Or that someone is migrating from another Markdown server application.

I think that allow relative paths between docs and images is an important feature.

[gilbitron]

Ok fair point. I can't merge this now as I made a major change yesterday but will look at implementing it myself (unless you want to resubmit a pull request using the new code).

[paulodiovani]

Ok, I'll try to merge your changes and then, submit a new pull request.

What about the ignore dir feature?

Do you plan something else for that or may I submit the patch again?

I would prefer to use a hidden .ignore file, but some users may get confused with hidden files (specialy on Windows).

[gilbitron]

I like the ignore feature but submit it as a separate pull request. I agree that the file should just be ignore to keep things simple.

Also just so you know this kind of functionality has been moved to https://github.com/gilbitron/Raneto-Core
