1. Added Richard Purdie's general editing feedback to the "Welcome" and
"Introducing the Yocto Project Development Environment" sections.
2. Added Kevin Tian's feedback: 1) changed "Sudo" to "sudo", 2) reversed
the order of the sample "cd" and "source" commands since the "source" command
builds the directory structure first so changing to the directory before running
"source" made no sense, 3) removed the "bitbake qemu-native" command.
