Fixed up smaller changes

Going forward, I don't see why we need:
- Closed issues, version number. Because these two are essentially meaningless as a way to compare packages. What does it mean that one has more closed issues than another? Does a pkg 1.5 and another 0.3.3 mean something?

Improvements:

- Now you get the description as a tooltip for repo name
- You can sort by last commit date (which also sorts the commit sparkline)
- There is a timestamp of last generation at the bottom of the table
- CRAN status is correct
- Deep links to more metrics.
