tablex: Add deep & shallow for copy, overlay

Replace copy with shallow_copy, deep_copy.
Replace overlay with shallow_overlay, deep_overlay.

the note above them.
Add corresponding tests.

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.

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.
