Awakening of Evil

Decided to re-upload the campaign. The changes are minor – mostly fixing typos in the dialogues. Important changes: 1) In the second mission, I revised the approach to experience reduction again. I removed the percentage-based experience reduction and added an absolute value. Now, the hero always remains at level seven. 2) In the fourth mission, I fixed a bug in the spell library that prevented learning one third-level spell from the school of light. 3) In the fourth mission, I limited the number of buyouts of secondary elf heroes in the tavern. Now, Vinrael will not be resurrected indefinitely.
