Title: Implemeting help message for servo browser app using groups::opts module.

Executing servo browser for the first time doesn't make evident that it already supports several different flags.

This patch implements a help message displaying the available options and a brief explanation on them, based on comments in source code (opts.rs).

I implemented both short hand/long hand options using getopts::groups.
