Added New Route Options as per Comment by ross

## New Route Adding Options
I added some new ways to add routes as per a comment left by ross on the NetTuts article. These changes are backwards compatible, and the old method will still work.

### The Options:

#### 1) Key - Value (The Original Way)
```php
$routes = array(
    '/' => '',
    '/test/:title' => 'Main:test@get'
);
```

#### 2) Array (Route, Action)

This is from the comment on NetTuts, it is in-order that you can have multiple routes pointing to the same endpoint. (e.g. different methods)

```php
$routes = array(
    array('/home', 'Main:displayhome@get'),
    array('/home', 'Main:addComment@post')
);
```

#### 3) Key - Array

This is a mix of the two, providing a slightly nicer syntax.

```php
$routes = array(
    '/users' => array(
        'get'     => 'UsersController:displayUsers',
        'post'   => 'UsersController:addUser',
        'delete' => 'UsersController:removeUser'
    )
);
```

And of course the 3 different options can be mixed and matched so your route array can look like:

```php
$routes = array(
	'/' => '',
	'/test/:title' => "Main:test@get",
	
	array('/arr', "Main:index@get"),
	
	'/demo' => array(
		"get" => "Main:test2",
		"post" => "Main:test3"
	)
);
```
