More Polish

Following submission of the game to the jam I have continued to work on the game adding some bugfixes and features I felt were missing.

• FIxed issue with lavender potion effect animation. It wasn't very obvious with the game as it was but it didn't follow the same pattern as the other potions.
• Added pouring animations.
• Added a score tracker and end game screen so people can see when they've found all the spell combinations.
• More sound effects to make the spells feel more alive and magical.

I have updated the Windows and Linux downloads. I will update the HTML version once the jam's rating period is over.

For purposes of rating, please keeping use the HTML5 version OR the downloads that end with -jamVersion in the filenames.
