Undocumented\Unused `ScriptFile` option

[Drgabi18]

As the title says, while the example skins have all the necessary info to do what is necessary in this skin, there seems to be an option that isn't in any of the examples

Line 53 gets the ScriptFile option and Line 75-91 do... something with it, I can't understand what from looking at the code, but it seems to just be something done to make it easier to call a JavaScript function every Rainmeter (plugin) Update()

Without knowing, I believe this may have been suppressed after the author realized <script src="./script.js"></script> dose the same thing (that is, for self made pages, this option may still be helpful for injecting JavaScript on online pages like YouTube).
