Indemon Tales 1.264

- Added a sword swinging effect
- Added a final floor to Deathwind Cave
- Added two new artifacts and removed Soul Union artifact (deprecated ever since party members could use special attacks on their own)
- Runes of the same type can now be stacked for space saving purposes (stacked runes don't grant bonuses)
- Item stack amount now displays numbers higher than 999 (overlaps with other items if the number gets too big, tho)
- Nicer sprites for gem items
