add usage of application.root parameter
rename parameter "root" to "app_root"
[COOK-2395] Add a root path (default to /)

This was originally applied to opscode-cookbooks/application. It turns

application cookbook's resource.
[COOK-2395] - adjust app_root attribute

The app_root attribute is moved to this cookbook rather than being in
the application cookbook.
[COOK-2510] Change app_root to mod_php_apache2 resource attribute.
