Fix color lists

[ninjaguardian]

Lists of colors were not correctly passing focus.
This also adds a list of colors to the test gui.

(It also fixes two stonecutter issues that were preventing me from compiling)

The main branch has this issue too, but it's much more complicated. The fix in this pr does not work for it, and the 3 minecraft versions respond differently to fixes.

I meant to rename it...
Oh well.
lts: #351
main: #350

I also separated out the stonecutter fix into its own pr: #352

In 26.x, ContainerEventHandler.super.setFocused(boolean) got an impl, which was causing issues.
