#websrv

This is a simple web server expanding on the example given in the Rust book. At the present time, it answers with static html.

TODO:
* Also answer css requests, pictures, etc => OK
* Fully integrate the config path => Ok
* Gather info about the client (IP, User-Agent, etc) to do funny stuff with it => Just printing client's adress for now
* Use arguments => Done, clap is very very nice !
* Not satisfied with the way root_folder is handled, being passed on from one function to another.
