Lua Scripting

-Use static pushback vector that contains the lua state, the filename and status booleans (started, savestates etc)
-When emulation starts Init() gets called: Find all lua files that start with an _ and add them to the vector to be launched immediately
-On shutdown of emulation remove all active scripts and delete the lua states so the user can edit the files
-Have Launch Script UI under Zelda tab that refreshes a dropdown list of all script files every time it is Shown (closed and re-opened)
-Launching a script places it inside the vector as well, also have button to cancel a script and remove it based on filename to allow quick editing
-Split superswim and normal script update calls in SI_GCController
-Normal script updates check all lua states in the vector, check if a script needs to be launched (hasStarted = false) and updates all the started ones (scriptUpdate, scriptStart, scriptEnd)
