This makes the kioslave work on KDE 4.1 for me.

Changed implementation of filesystem from using Host and User (like a remote protocol) to use a just filesystem approach.

The first component is Camera Name @ GPhoto port, the second
until the end the path on the camera.

camera:/Camera Name@GPhoto Port/first path/

Working:
- direct open and viewing

Not working:
- Copy to file directory? Strange, looks like a incorrect setting.
- Thumbnails? Unclear what is wrong.
