Major reorganization

Hey all. In the interest of code/file organization, I have reorganized the CSE Club site in a big way. Given the sizable changes present in this commit, I am making a pull request. Please look through it and let me know if you'd like it merged.

Note that as it stands it will break existing links. If need be I can add in placeholder pages that do nothing but redirect to the new pages. Let me know if you want that done.
