Figure out a more elegant solution to always re-loading required modules

The whole point of this is to be able to change values on the fly, and to accomplish that, the `"require"` `LuaFunction` (created in the `ScriptService`, inside of the `ConfigureStandardLibraries()` method) will always re-load any module that is required.

It seems like a better strategy could be only re-load certain modules that are prone to change with some sort of flag, or maybe another argument provided to `require` that will tell the module loader to always reload it, and otherwise it will cache loaded modules.
