V 0.6.2 balance update

This update mostly focuses on the classic third wheel, Nicholas!
I've gotten some complaints that he was too weak, and after thinking about it, decided they were right about that.

Nicholas will now unlock all fire and ice spells all by himself once he levels up enough!
Also, he will learn 2 unique spells that only he can use:
-Crystalize - VERY costly spell that has a 70% chance of stunning a single target for one turn
-Wall of Flame - Cheaper version of Fire Storm that does less damage but still hits all enemies, and has a 100% chance to set them all on fire
-I also boosted the starting levels of Nicholas and Katrina by 1 in all difficulties (Note: In the intro Nicholas is still level 1)

Other balance changes:
-I MASSIVELY nerfed Wine and the conversion spells, someone pointed out that they were basically broken with how OP they were.
-Minor quality of life change - The game will no longer autosave after each battle, only when you travel to a new area.
-Clarified how long the player has to wait at the start, and reduced the wait by 1 day. Now you only need to wait 5 days to start the main questline.
-Samuel will now start the game well fed, giving the player an extra day to sort themselves out before they start to starve.
-I increased the range of the torches in the first crypt, and sped up the crypt zombies a little.

-And finally, I nerfed the Master Necromancer a little, his magic defense is now 45 instead of 50. This should make it a little easier for Nicholas to damage him with magic, assuming he's high enough level of course.
