Title: add_post_type_support and remove_post_type_support for Custom Post Types

Added methods to Cuztom_Post_Type, wrappers to add_post_type_support() and remove_post_type_support().

**add_post_type_support()** enables support for specified features in addition to default features, while the supports argument while creating a custom post type enables support for only specified features.

Example, item created by the following code will not have title and editor but will have thumbnail
```PHP
$item = register_cuztom_post_type('Item', array('supports' => array('thumbnail') ) );
```
but the item created by the following code will have title and editor as well as thumbnail
```PHP
$item = register_cuztom_post_type('Item');
$item->add_post_type_support('thumbnail')
```

**remove_post_type_support()** can take either a single string feature or an array of features unlike [WP remove_post_type_support()](http://codex.wordpress.org/Function_Reference/remove_post_type_support) which can take only a single string feature
