File class improved debugging and filename generation

Browse Source 
In some development code I noticed that when handling File objects without
filename values, there would be problems calling getPath and such.

The width and height value testing will be validated later anyway, and by
removing such a narrow test we can use events to generate thumbnails of
media formats supported by recently added plugins on demand.
