This release doesn't change the basic functionality of ufov.

It fixes a bug that in order for statistics to be shown in the ufov window, they had to be printed to the terminal. Now, the two are independent.

Added new options to the config file that allow the statistics to be appended to a file. The default file will be called ufov_results.txt and will be written in the directory where ufov.py is, though you can set the name and path for it. This allows a record to be kept of historical performance. More fully described in the documentation.

Added new options to the config file that enable early results to be excluded from the averages. This allows the learning curve for the sprites to be excluded so only experienced responses are included. The actual operation is a little convoluted, so see the README, the ufov.html, or the web site for an explanation.

All of this should be backward compatible, thus only a minor bump to 2.2.
