Allow other node types to also be categories / containers (completed)

The categoryi module currently allows two methods for category or containeri nodes to be created.

The first method is by using the native category and container node types: the user simply goes to 'create content -> category / container', and submits their node. The second method is by using the 'category' and 'container' menu tabs, that allow nodes of any other type to be transformed into a category node type (and to still natively be their original type).

A very handy third method would be to set any other node type to also 'be' a category or container, by setting it to be this way in the 'administer -> settings -> content types -> type x' section of a site. This would be analogous to the way that the event module allows any other node type to also 'be' an event.

This third method may be more convenient for many users, and may also offer significant advantages. For example, a site administrator may wish to have all categories created with certain additional fields: if so, they could simply set a special custom node type (such as one made with flexinode) to be a category type; and they could then force users to only create categories of this type.
