* Try to clean up asset folders for sample apps. This removes the build step where we copy a subset of assets, and makes it so that FilamentApp hands out a "root path" for assets. For now this is determined based on the location of the executable. This allows developers to launch samples from any CWD. Closes #11 * Restore asset copy to build.
