Dev 1.0 First Pull Request

Since you are extracting thread comments here, I think this should be moved in thread model. If you do this, in comment_controller.php, instead of doing this
```php
$thread = Thread:get(Param::get('thread_id');
$comments = Comment:getComments($thread->id);
```
can be changed to this which is more logically correct.
```php
$thread = Thread::get(Param::get('thread_id');
$comments = $thread->getComments();
```
