Polyfill table.move for 32-bit Gmod

[Denneisk]

Implements table.move for 32-bit Gmod as accurately as possible, including errors, to preserve forward-compatibility. This solution is, naturally, not completely optimal.

Comment out the if statement and rename the function to compare outputs.

PrintTable( table.move( { 1, 2, 3, 4 }, 1, 4, -4 ) )
--[[ Outputs:
-4	=	1
-3	=	2
-2	=	3
-1	=	4
1	=	1
2	=	2
3	=	3
4	=	4
]]

Additionally, the documentation on the wiki is incorrect. The 4th argument, dest, is required (you can test this yourself).

LuaJIT will be upgraded on main when it's branch merge time. I don't see the need to implement this in Lua right now. Servers can do it themselves for main branch clients.

I don't think this will happen any time soon. We have been in limbo state on several awaited features for YEARS by now. So better account for things taking a while, then speculate on "soon™". Things taking time, that's how it is. I personally expect it to take at least another 3-5 years until we come to a conclusion on that matter.

So add polyfills as long they are needed for the time being, especially then they were already done for you via a PR. If you want cross branch-compatibility than do it properly. Otherwise it will just create additional unnecessary community pressure on the dev.

I have seen a lot of tip toeing around over potential braking branch-compatibility changes over the years. So at this point a "well do it your self" on a PR doing the same tip toeing is just ridiculous.

Could be cleaner if assert was used.

        assert(istable( sourceTbl ), "bad argument #1 to 'move' (table expected, got " .. type( sourceTbl ) .. ")" )
        assert(isnumber( from ), "bad argument #2 to 'move' (number expected, got " .. type( from ) .. ")" )
        assert(isnumber( to ), "bad argument #3 to 'move' (number expected, got " .. type( to ) .. ")" )
        assert(isnumber( dest ), "bad argument #4 to 'move' (number expected, got " .. type( dest ) .. ")" )
        if destTbl ~= nil then
            assert(istable( destTbl ), "bad argument #5 to 'move' (table expected, got " .. type( destTbl ) .. ")")
        else
            destTbl = sourceTbl
        end
