Bestiary in the title and pause menu; attacks look bigger with the unit level

- tabs: creatures, humans (incl. cave dwarves), dungeon buildings and towers, ranks
- every unit at every level: sprite with gear, rank badge, health, attack, range, speed, wage or bounty, what attracts it
- Crookfinger's texts: loving about the creatures, disgusted about the humans (EN/DE)
- projectiles, hit sparks and splashes grow with the attacker's level, with halos from Lv 5 and glow at Lv 9+
