Adding six new dependencies for current php cookbook

The php cookbook that is installed in Chapter 1 [has added](https://github.com/opscode-cookbooks/php/blob/master/metadata.rb) three new dependencies: `yum-epel` (which itself has a dependency of `yum`), `windows` (which has dependencies `chef_handler` and `powershell`), and `iis`.

This updates the `chapter1.sh` shell-script, as well as the html in Chapter 1 and 2 to reflect the new dependencies.
