Recent feature bugfixes and code cleanup

Moved all knockout update code to the KnockOut.pwn script under it's own
function.

Increased the time it takes to heal a knocked out player (known as
revival)

Fixed a problem with incorrect use y_iterate's Iter_Remove inside a
foreach loop. It now uses Iter_SafeRemove properly.

Improved MovementDetection with more exceptions and a delay if the
player recently exited a vehicle or was travelling very fast.

Added scriptfiles folder structure. This isn't the actual scriptfiles
that is run on my server, but a mock-up folder of what it should look
like. I just removed my level designs and any account data. There are
also readme files explaining what each folder contains.
