UI: Thoughts tab on Overview

[andyprogrammer]

I find I often want to prioritize what to work on by looking at colonist moods. It would be great if we had a window that was an aggregation of all the colonist Thoughts and their total +/- mood effects. For example "Ate raw food" might show -49 because 7 colonists are currently getting a -7 mood each. Then you can expand that thought to see the 7 colonists who had that thought, and click on one of them to jump to that location.

The folding elements would work like the Stockpile widget, only with Thoughts.

Putting this in an Overview tab would be where I would look for it, although that is getting crowded lately.

It can be one of the history graphs.
