Documentation: update dev-guide.md and examples/README.md

- Be more explicit with exact instructions to startup
- Change some of the commands that were using local directory with "./" when
    the executable was in a lower directory. These
    commands (like "./bin/dex-worker") did not work on ZSH or Bash, so I
    removed the leading "./"
- Add some syntax highlighting markdown to code sections
