vii a87373d003 feat(assets): let the overlay replace files Roblox downloads
Roblox maps some rbxasset:// names to downloads and opens no local file for
them. For each file under content/ in the overlay folder, change its name in
the loaded libroblox so Roblox opens the local file.

Idea from @dim-ghub in #20.
