UI Texture Update

[careeoki]

Updates UI textures to match the newest block textures. Also improves the legibility of icons.
Fixes #373 and fixes #361


Note that the hotbar is now opaque. I think it being translucent was nice, but to do that we need another texture/some code

My thoughts

• looks a little too cartoonish for my taste
• scroll bar is really thin
• the checkboxes are amazing!
• +/- zoom icon is more intuitive
• red cross icon looks out of place in thickness and it's also somewhat out of bounds

I can't change the scrollbar because it is made in code, which is not my department. Same with the icon spacing/window title height.
Here's a different X:

This X looks a little more natural.
The inventory slider width is defined here if you want to try: https://github.com/PixelGuys/Cubyz/blob/master/src/gui/components/VerticalList.zig#L16C24-L16C25

so much better!

[archbirdplus]

Lol, you replaced all the tabs with spaces trying to edit that one line.

[careeoki]

I warned you!
The value 10 looked good. Someone else can do it for me in 30 seconds.

Personally, i would say, the bigger red cross, looked better, but anyway:

could you make the inside of the red cross, a bit brighter for more contrast?
Compared to the zoom buttons,the cross doesn't seem to have that much contrast.
or maybe it is just me?

See my PR on your PR. (?)

I prefer the thin red cross.

I'm ready for this to be merged.
