Fixed a long-standing bug in the Thunderball Ticket Checker - the cache filename for the generated GIF wasn't using the Thunderball number as part of the filename, so it was possible for two people with the same main numbers but a different Thunderball number to "interfere" with each other's generated image. The Thunderball number is in the filename now, so this shouldn't happen in the future.
