Wiki spring cleanup - TOC pages

[antoviaque]

The goal is that any member of our community should be able to navigate the public page tree and feel confident that they're looking at relatively fresh information (or, when appropriate, clearly-marked old information).

For the Technical Oversight Committee page tree:

• Update any pages that need refreshing.
• Archive any pages that are completely out of date (ping Feanil if you don't have permission to do so).
• Reorganize and rename pages as you see fit.
