Megumumpkin da6a2e53ba New Lua Scripting (#501) 
* New Lua Scripting System

* Update Scripts

* Small fix on wiLua Globals

* Add One More Note To The New Demo

* -path fix
-renamed new_script_demo.lua to script_tracking.lua
-refactors
-version bump to 0.71.0

* removed GetScriptPath()

-- Lua Fighting game sample script
--
-- README:
--
-- Structure of this script:
--
-- **) Character "class" - holds all character specific information, like hitboxes, moves, state machine, and Update(), Input() functions
-- ***) ResolveCharacters() function - updates the two players and checks for collision, moves the camera, etc.
-- ****) Main loop process - initialize script and do call update() in an infinite loop
--
--
-- The script is programmable using common fighting game "numpad notations" (read this if you are unfamiliar: http://www.dustloop.com/wiki/index.php/Notation )
-- There are four action buttons: A, B, C, D
-- So for example a forward motion combined with action D would look like this in code: "6D"
-- A D action without motion (neutral D) would be: "5D"
-- A quarter circle forward + A would be "236A"
-- "Shoryuken" + A command would be: "623A"
-- For a full circle motion, the input would be: "23698741"
-- But because that full circle motion is difficult to execute properly, we can make it easier by accpeting similar inputs, like:
-- "2684" or "2369874"...
-- The require_input("inputstring") facility will help detect instant input execution
-- The require_input_window("inputstring", allowed_latency_window) facility can detect inputs that are executed over multiple frames
-- Neutral motion is "5", that can help to specify in some cases, for example: double tap right button would need a neutral in between the two presses, like this: 656. Also, "5A" means that A is pressed only once, not continuously.
