The addition of dependencies in commit 52fc535d26
was incomplete, so loading the moremesecons_timegate mod can fail.
This change adds the moremesecons_utils dependency to those mods which
require the moremesecons table as reported by luacheck.
I've also made .luacheckrc more strict so that it sets globals per mod
and allows reading the moremesecons table only in mods which also have
the moremesecons_utils dependency.
* Use opaque use_texture_alpha for the timegate and dual_delayer
This avoids warnings shown by Minetest and improves the nodes' look when a bilinear filter is enabled.
Since the textures are also used as inventory images, I didn't remove the transparency from the texture files.
* Luablock: Fix the missing position argument when executing the lua code fails
* Wireless: Fix the missing id argument
* Localize several variables
* Some other small changes, e.g. dead code removal
This reduces the PNG file sizes and fixes the invalid sRGB profile warnings.
I have additionally reduced the moremesecons_luablock.png resolution to 32x32.
