[bug]: loadfile can fail with no error message displayed

[Beanzilla]

Lua docs on loadfile, state it can return nil and a error message, or a function.

So we can optimize the code so it can either stop the server because of this error and display it, or just log the error and continue in a disabled state.

Snip of init.lua L66-L82 (in the "Import boosts config" section)

local boosts = dofile(minetest.get_modpath(minetest.get_current_modname()) .. "/boosts.lua") or {}

local worldboosts_file = io.open(minetest.get_worldpath() .. "/boosts.lua", "r")

if worldboosts_file then
    -- boosts = loadstring(worldboosts_file:read("*all"))() or {}
    local loaded
    local err
    loaded, err = loadstring(worldboosts_file:read("*all"))
    if loaded == nil then
        -- Your choice
        minetest.log("action", "[Boosts] Failed loading world-specific boosts config")
        minetest.log("action", "Error: " .. err)
        -- OR
        error("[Boosts] Failed loading world-specifc boosts config, got error: " .. err)
    else
        boost = loaded() or {}
        worldboosts_file.close()
        minetest.log("action", "[Boosts] Using world-specific boosts configuration")
    end
end

if get_table_length(boosts) == 0 then
    minetest.log("warning", "[Boosts] No boosts configured")
end

I recommend just logging the error and continue on with default (from within mod directory), but you may prefer to stop the server on load of invalid configuration.

The nice part with this is either way our user gets a nice error message on exactly what failed

Like in my case I was miss typed a period . instead of a comma , when I was building my boosts.lua in the world directory.
