Fix: Menu cache not created/updated on startup. (#8)

ST ignores the `sublime.run_command("refresh_theme_cache")` command in the `plugin_loaded()` function.
Therefore we need to call the command directly to make it work properly.

Paths are created using the `os.path.join()` function to built consistent paths on Windows/Linux/OSX using the correct path separator.
