Title: Added a page for unsafe operations

It is not the most in depth, but after looking at the other pages in the book it seems to match the coverage. Plus, there is an official [rust tutorial](http://static.rust-lang.org/doc/0.10/guide-unsafe.html) for unsafe code which will suffice for a more in depth explanation, whereas this page serves as a quick reference and getting started point.
