Refactor most files for loading, drawing, and input checks

Changing up the process needed to add a new screen to the Tracker. In the past, this would require adding pieces to various files so that the screen would be loaded, initialized, drawn, and input check for buttons clicked. This refactor simplifies that process so they only need to be added in a single place: FileManager.lua

This refactor automates the process for adding screens and drawing them, as well as adding individual input check methods to each screen. This implementation is outlined below.

Overall, this should make it easier for new additions, especially for any devs of new extensions. Long term I want to normalize the template for each screen to have Labels and Colors and other things, as well as better ways to create Button objects to make it even easier.

New Initialize Template (automatically applied to screen files with an initialize function)

for _, luafile in ipairs(FileManager.LuaCode) do
    local luaObject = globalRef[luafile.name or ""]
    if type(luaObject.initialize) == "function" then
        luaObject.initialize()
    end
end

New Drawing Template (automatically applied to screen files with a drawScreen function)

if Program.currentScreen ~= nil and type(Program.currentScreen.drawScreen) == "function" then
    Program.currentScreen.drawScreen()
end

New Input Template (automatically applied to screen files with a checkInput function)

if Program.currentScreen ~= nil and type(Program.currentScreen.checkInput) == "function" then
    Program.currentScreen.checkInput(xmouse, ymouse)
end
