Removed unused section links and fixed page height

- The latest version had all of the new sections added in the menu but they don't all have chapters in them ready for publishing.  Removed them from the "Other Guides" menu, and also coded the menu so it will be automatically generated.

- Added Javascript to automatically set the min-height of .doc-main based on height of nav menus.


Still needed is some help styling the "Other guides" menu, and finding a solution for editing the homepage toward the new guides.
