Leap day addon

Leap day occurs only once every four years, on February 29th. Because of the rarity of this date, several badges have the leapday addon to reflect this. The affected badges and requirements are as follows:

• The Achiever: Find at least one challenge cache on Leap day.
• The Adventurous Cacher: Find at least one 5/5 cache on a Leap day.
• The All Around Cacher: Fill all 360 sectors with finds on Leap day.
• The Ape Cacher: Log at least one Project A.P.E. Cache on Leap day.
• The Attribute Cacher: Log geocaches with all 103 attributes on Leap day.
• The Brainiac: Find at least one Difficulty 5 Geocache on Leap day.
• The Busy Cacher: Log the amount required for Diamond (400 caches), on a single Leap day.
