Subject: [PATCH] LoadFileToVector: Fix a bug that empty file size was an error
 case. If the file is found but the contents is empty we return true but log a
 warning as this is a unusual situation. Add a single space to
 data/assets/dummy.txt so it wont spam these warnings on the local storage
 roaming step when tundra is ran.
