Issue 230 specifiy that: The apache::mod::* classes that have .conf file

resources don't refresh the service when the configs are updated, but they
should. (https://github.com/puppetlabs/puppetlabs-apache/issues/230).

This commit fixes the issue by adding:

        notify  => Service['httpd'],

to all file resources.

Note that the modification has only been tested with a few of the modules.
