Updates to next/prev link handling
added note about website size and 7zip format
Rewrote css to use classes in a unified scheme for the buttons
appearance eliminating most special case code
Significantly more stuff now works in the sidebar department.
Further refinements to appearance. Used box-sizing to solve alignment
issues. Set float and position for consistency. Fixed duplicate #menu
(now #table-of-contents).
Sidebar now enjoys considerable persistence. I've basically made it's
state totally persistent within a session, including whether it's open
or closed and the selected tab.
