Prevent computers from freezing on the BIOS node
after Minetest is restarted by adding a `booting`
flag to all computers waiting for the two seconds
to be over before the BIOS node is replaced with
the on node and by adding a coroutine which loops
through all the computers and replaces them with
"on" versions if they are stuck in BIOS.
Mod would load but would crash upon giving the computer input. This was a result of the base OS files not being copied meaning that the "code" variable would be nil. Bundled in this commit are other related changes improving the overall filesystem-related stability on Windows. TODO: prevent crash when missing important files like main.lua
This introduces a small API allowing different portions of the mod (digicompute) to be divided among sub-mods (modules) in the modules directory. See documentation for further information (modules.md).
