Update manifests/module.pp

Remove obscurity of $source declaration for modules.
We can surely add the previous behavior as an append if needed, but I found myself forced to read the source code to understand how it works.
Also, this code is incompatible with possibilities, like multiple folder/file choices, so I consider that this native "feature" should be removed.
Here is my example use case:

```
php::module { 'php-apc':
    name           => 'apc',
    package_prefix => 'php-',
    notify         => Class['php::fpm::service'],
    source         => [
        "puppet:///modules/instaclick/php/conf.d/apc.${env}.ini",
        "puppet:///modules/instaclick/php/conf.d/apc.ini",
    ],
}
```

Update manifests/conf.pp

Remove obscurity of $source declaration for conf.
This follows the same previously submitted PR for modules. It allows multiple folder/file choices, so I consider that this native "feature" should be removed.
Here is my example use case:

``` 
php::conf { 'pdo':
    source => [
        "puppet:///modules/instaclick/php/conf.d/pdo.${::env}.ini",
        "puppet:///modules/instaclick/php/conf.d/pdo.ini",
    ]
}
```
