Make the impact page tell the story of BIDS' impact

[ericearl]

Take a first pass at improving the Impact page to be more about the Impact of BIDS. Even if this means just moving the current content around and re-using the last BIDS town hall slide content.

from #481

Reorganize the impact page:

• Reorder content to show metrics, history, deliverables, and place how to cite etc etc at the very end/bottom of page
• Integrate slides from OHBM into impact page, no reason not to use existing work.
• Add/update paragraphs/statements for existing content? @iamdamion @ericearl update this item.
