More Saviour Schnapps

These changes aim to ease access to Saviour Schnapps at higher Alchemy levels to remove some tedium. I try to keep some gameplay integrity by reducing their utility as a money maker or health potion at higher qualities. Weight is halved to somewhat compensate for the (potenitally) higher amount carried.

- Max yields changed from 2/2/3/3 to 2/7/12/17

- Weight changed from 0. 2 to 0. 1

- Healling changed from 0/10/20/30 to 0/5/8/10

- Prices changed from 250/300/400/550 to 250/100/100/100

I balanced the price changes around default modifiers, so without perks. For Saviour Schnapps specifically, Secret of Matter rounds the values up nicely to 5/10/15/20 but every extra potion is worth less due to the base price going down (compared to the base game).

The yield change is compatible with anything that doesn't change the Alchemy Recipes. The other changes should be compatible with anything that doesn't affect Saviour Schnapps (or overall potion) weight/healing/price specficially.
