Player score reset

[sporksmith]

Twice when running the game, the player data was reset. This caused all calls to drop (since the Tropo sessionid's for the live calls were no longer in our database), and player scores to reset.

After reviewing the server logs, it appears the player data was manually reset through the dashboard page. (i.e., posting to dance_ave/dash). I suspect this was done by accidentally re-POSTing after a reset by refreshing the dashboard page to see the updated player scores. While the browser should (and probably did) warn about re-POSTing data, the consequences may not have been clear.

To avoid this, we should use the Post-Redirect-Get pattern.

We now use the Post-Redirect-Get pattern to avoid this (commit 28a9891)
