Routing: Dont strip the s from the resource id to prevent possible weird behavior with irregular english plural nouns

# Addresses the following problem:

If a user creates a resource **accounts** for instance, the **s** at the end is stripped for the id paramter so the id would become **{accountId}** in the url. This can lead to a number of various weird behaviors if the plural is not regular: e.g.:

* **knives** -> **kniveId** (instead of **knifeId**)
* **series** -> **serieId** (instead of **seriesId**)
* **species** -> **specieId** (instead of **speciesId**)
* etc. 

Rails solves this by shipping a dictionary containing those exceptions but I think it's out of scope to ship exceptions for the english language. 

Therefore I think its better to get rid of that behaviour alltogether and use **{id}** as the key (a resource has only one id anyways) e.g.:

     'resources' => array(
        array('author' => array('url' => '/authors'))
    ),

will turn into:

    'routes' => array(
        array('name' => 'author#index', 'url' => '/authors', 'verb' => 'GET'),
        array('name' => 'author#show', 'url' => '/authors/{id}', 'verb' => 'GET'),
        array('name' => 'author#create', 'url' => '/authors', 'verb' => 'POST'),
        array('name' => 'author#update', 'url' => '/authors/{id}', 'verb' => 'PUT'),
        array('name' => 'author#destroy', 'url' => '/authors/{id}', 'verb' => 'DELETE'),
    )

instead of

    'routes' => array(
        array('name' => 'author#index', 'url' => '/authors', 'verb' => 'GET'),
        array('name' => 'author#show', 'url' => '/authors/{authorId}', 'verb' => 'GET'),
        array('name' => 'author#create', 'url' => '/authors', 'verb' => 'POST'),
        array('name' => 'author#update', 'url' => '/authors/{authorId}', 'verb' => 'PUT'),
        array('name' => 'author#destroy', 'url' => '/authors/{authorId}', 'verb' => 'DELETE'),
    )

This may break backwards compability though which is why I'd prefer to get this into 7 before it is released.
