Renaming a level asset does not move scripts to a new __BangoScripts__ content subfolder

[HomerJohnston]

Right now nothing breaks... but any existing scripts will stay in the original level subfolder, which could cause confusion. Adding scripts to a level before it is saved will put them into an "Unnamed" level folder, which is very confusing. fixed this by preventing creating level scripts until a level is first saved.

I should write some sort of command to fixup scripts after renaming a level.

It should not be too hard to parse all of the scripts in an open level, check the level name from the script path, fix the property (it's just a soft pointer), and move the .uasset files.

It should also be possible to manually instigate this check for a level.

Alternatively I should just rely on UE's normal systems: when a level is renamed, move all script assets to a new folder. Let the engine produce redirectors. Then fix them up automatically, because the moved level will always need to be checked out anyway.

This might not automatically handle the edge case of adding scripts to an unsaved level.
