deleted php coockbook as it was causing conflict with default opsworks default cookbook
updated phpenv environment variables recipes to support to methods to add env vars. 1) using htaccess files. This recipe requires two additional parameters: htaccess_emplate (to support templates other than the default one), and path_to_vars (the path from the project root to the location where the file will be placed ie: web, public). 2) php env vars using putenv. This requires the environment variables be retrieved using getenv, it requires an additional parameter: path_to_vars. This is the path to the location of the file (where it will be created) ie config/environment.
