A handful of improvements

Hi all,

Just a quick post to note a few recent modifications:

Play vs. Computer - You can now navigate back & forth.  Jump around in the game history, and try something different from wherever you like.  We've also added a button for quick access to the game's PGN.  Check it out!

We also made a small fix to personal themes.

We fixed a bug related to tracking people removed from one's Friend list.

Finally, we made the system's "Timeout Percentage" tracking a little more forgiving, while still keeping it relevant:  The metric is now based solely on games ending in the last 90 days.

That's it for now!

Cheers
