Example modules need updating for 5.0

Updated block_example and page_example modules.

Still to go:
- fileupload.module
- filter_example.module
- multipage_form_example.module
- node_example.module
- nodeapi_example.module
- xmlrpc_example.module

Pants module is cool, and gets across a lot of concepts, but imo isn't appropriate for API documentation.

and before I get flamed for that, I don't mean inappropriate as "OMG PANTS?!?! Won't someone think of the children!!!" I mean it as in each example module in the API docs communicates one specific concept, and is only a few functions in length. Pants module covers everything from hook_user to XML-RPC. It's more of a tutorial than an example.

Here's a start on nodeapi_example.module. It should be working, except it isn't. :P For some reason, every time I save the node settings options, it saves it as nodeapi_example_blog_blog which of course doesn't work. But even correcting manually doesn't seem to be working either.

Here's the info file.

Whoops. Accidentally committed that while I was committing an info file for XMLRPC example. :(
