Tiny Core file architecture diagrams added to Wiki

[Rich]

Thanks to ixbrians efforts we have some outstanding system diagrams that show how Tinycore works. Unfortunately,
the only links to those diagrams I see are in the thread that announced their existence. I feel these diagrams should
have much greater visibility, so I created a brief Wiki page that contains the links to them under:

How it Works->Tiny Core file architecture diagrams

These diagrams are bold face links in Core Concepts which every new user should peruse.

Hi roberts
So they are, guess I should have payed closer attention. Regardless, I still feel they warrant an entry on
the Wikis index page.
