d48d4b0e81 table: Rewrite *_copy to copy any kind of type
Allowing shallow_copy/deep_copy to accept any type makes it easier to
write generic code where you just want to copy some input without
knowing anything about it. Like an event system, save system, etc.

Add corresponding test.

Tests pass

9083ee74ca lint: Fix accessing undefined append_inplace
Fix crash when using append_inplace without batteries:export().

If you don't export batteries into the global namespace to stomp table,
then append_inplace would access a nil function because it's using table
instead of tablex.

We still use table inside init, but that's after we export to global
namespace.

a5ebc1e501 lint: Fix shadow issues
Fix shadowing by using variables with a different name or _.

I don't think any of these warnings were actual bugs and fixed them to
maintain the same behaviour.

5fa80ca97c tablex: Add deep & shallow for copy, overlay
Replace copy with shallow_copy, deep_copy.
Replace overlay with shallow_overlay, deep_overlay.

Significant rewrite of these functions and their semantics to update to
the note above them.

Add corresponding tests.

5b4d1c16c5 tablex: Skip equality comparison in equal fn
The second loop doesn't care if the values are equal. It only checks if
the keys are there. The first loop already checked for equality.

Add tests to prove correctness using testy.lua.

a42f1190e0 Modified weighted random pick function
- Now accepts a table from which it will pick the random value from,
  instead of an index
- Changed function name to better reflect the way it now works

Fix shuffle to avoid bias
There's a subtle trick in shuffling: you should draw only from the part of the deck you have not seen!  Otherwise, some permutations are more common than others.
