More readable docs.

I rewrote docs from clonezilla site in markdown lang and it looks, imho, more readable and understandable. Could You see it and maybe use in this repo?

Rewroted docs: https://github.com/vihryn/clonezilla-docs

Mentioned repo is unavailable nowadays. Maybe it's time already to revamp or to close this issue...

See pull request #17. Please, by all means merge this pull request or make proper docs. The state as-is is just bad. Don't get me wrong, this is a great software and I still use it, but a lot of people could profit from prominent, thorough documentation. The formatting on the CloneZilla Live page is off. There are hidden pages you can only find through google or links on websites (try to find a page with some? ocs-sr options? It's not linked from the Live docs...). Can I preseed options ocs-sr without having to specify the complete command line. Probably, but no clue... There's lots of questions like this.
