Get rid of random print() calls

[Emojigit]

This PR gets rid of print() calls by either removing them or changing them into appropriate minetest.log calls. This PR is ready for review.

I think the prints in the Lua tube should stay, makes more sense than logging IMO.

The others are fine to be removed. (one of them was me forgetting to remove it :P)

Shouldn't really, while print is easy on better platforms Linux it is way harder to utilize on Windows. And I'd guess there's now days a lot more Windows players than before.

What it ultimately should do is exactly same what mesecons does (besides mod name):

local function safe_print(param)
	if mesecon.setting("luacontroller_print_behavior", "log") == "log" then
		local string_meta = getmetatable("")
		local sandbox = string_meta.__index
		string_meta.__index = string -- Leave string sandbox temporarily
		minetest.log("action", string.format("[mesecons_luacontroller] print(%s)", dump(param)))
		string_meta.__index = sandbox -- Restore string sandbox
	end
end

I would probably have used suggestion as I usually do but you can't add suggestions without changes and previous commit did revert changes so there were not enough changed lines for suggestion feature.

Looks good to me, did not test it but seems it should work just fine.

In game lua tube print function now also works same as mesecons.

Oh, this wasn't merged yet.
