Reverting transition from sandbox->live.
Move late date.

Late fee now begins at midnight on Jan 16 HST.  This allows regular fees to be charged through Jan 15, consistent with marketing material.
Update IPN scripts to account for price increase.
Page refresh on price increase.

We now provide a rudimentary countdown timer to alert users of the imminent price increase.  When the page reaches the deadline, it forces a page reload and thereafter uses the late fee player prices.
Improve countdown timer.

Now differentiates between seconds and minutes remaining.
Improve styling of fee increase warning message.
Extend warning interval to 10 minutes.
Fix PayPal button for Sandbox mode.
Revert live->sandbox->live.

This is technically a revert of two reverts (0ed8c7b and dfe495d).  This should put the branch back into live mode.
