#449 Touch-ups on clsc potion graphics (potions branch)

[Saiapatsu]

The aim was to fix some of the potions with poor or
reduced-looking color palettes, remove shadows and
rework Draug's red potions, which I didn't do yet.

I still consider the unique potion shapes to be derivatives
of Gervais's work because of the bottle neck.

License files are unaffected.

The zip contains the graphics and the .xcf project
I'm working in, which contains the original
Gervais potions for reference and my own studies
and modifications of them.

Thanks! I'll review when I'm able, and hopefully merge it into my branch.

I've added this to my potions branch, commit 9e6cfd28da7048effb56891801882a139ab2a1ee
