new name of mac's system

In section 3.1 'Preparing Redox', the book suggests using the cross compilers from glendc/gcc_cross_compilers. These no longer work, and are not being used in the bootstrap.sh script from the redox-os/redox repo. This closes #84.

mdBook uses pulldown-cmark. pulldown-cmark implements CommonMark. CommonMark, unlike Github Markdown, needs a space after # for ATX style headers. See http://spec.commonmark.org/0.27/#atx-headings

Elaborate the use of the bootstrap script. Include a word of caution in case dependencies already exist on the system and are skipped by bootstrap. Restructure the chapter to better distinguish between a manual setup and a script based setup.

Improved the language in the "Exploring OrbTK" section.

this step is different for Linux-, MacOS-MacPorts- and MacOS-Hombrew users,
therefore I provided this step for each of the 3 target groups.

It looks like virtual terminal usage has changed, so I updated this page. Feel free to correct me if I'm wrong.

fuse is not mentioned in the book as opposed to the README in redox repository

The `bootstrap` script works as well on MacOS X

Add `override` statement

Add an additional description of how to install the nightly version of Rust, using `rustup`.

`multirust` is now deprecated - now use `rustup`

The changes include:
- Editing for flow and understandability.
- Unifying how links are included in the source files.
- Adding an `About this Book` page to the introduction.
- Adding a few examples or new pieces of information I felt were
  lacking when I read the book.
- Unifying 'user space' and 'kernel space' spelling.
- Added myself to the authors list in `overview/welcome.md`.
