ENDLESS DUNGEON UPDATE #3

New update for the Endless Dungeon. Mainly, the leaderboard is much easier to understand now. We've also adjusted difficulty a little, actually making the hardest enemies, Heartless, less common.

In detail, this is the changelog:

• Improvements to rankings display, specially for the top 3.

• Removed Heartless enemies from all transitions minus the loop one in Endless Dungeon.

• Added new, hardest versions of the Heartless encounter in Endless Dungeon.
