Parse image references from markdown files

[konstin]

Currently (oranda 0.5.0-prerelease.1), images in the readme need to be in a folder called static. It would be great if oranda could instead parse the readme an copy all markdown image inclusions (![alt](path/to/img.png)), maybe even html inclusion that you sometimes need to use.

Additionally, it would be nice if oranda would warn about image that are referenced but not present.

Agreed! Better Markdown parsing (which this would be a part of) is definitely on my list.
