fixs

A small patch with fixes:
Fixed the text position in the Spellbook.
Fixed the darkening of the Astrologer's Tower window and corrected the text for the next week.
Fixed the text for sacrificing an artifact at the Altar of Sacrifice.
Fixed the jerky attack animation on Ornella's arena (her living version).
Also, the garrison and Sanctuary have incorrect window titles for heroes, but I couldn't find where to change them.
P.S. There are so many bugs in the game, it's just a mess.
