* In WASM build, user levels and doodads are written to localStorage
using their userdir path as keys (".config/levels/test.level")
* LoadFile() and WriteFile() for both Levels and Doodads interact with
the localStorage for WASM build instead of filesystem for desktop.
* userdir.ListLevels() and ListDoodads() for WASM scan the localStorage
keys for file names.
* userdir.ResolvePath() now works for WASM (previously was dummied out),
checks for the file in localStorage.
