[gthumb-list] gvfs-based photo importer

["Dr. Michael J. Chudobiak" <mjc avtechpulse com>]

Hi all,

I have committed my first attempt at modifying the photo importer to use 
gvfs with the libgphoto2 backend.

You may need to install extra packages on your system to use it. On 
Fedora, you need "yum install gvfs-gphoto2". Also, the distro-provided 
launcher scripts may not work correctly now, because they may unmount 
the gvfs mount point that we want to use now. If this happens to use, 
cancel the script and launch the importer from inside gthumb.

Right now, if you launch the importer from the File menu, it scans 
/media and ~/.gvfs/gphoto* for dcim directories, without input from the 
user. It tries to identify all image files in these folders.

It can be launched against particular dcim or non-dcim folders using 
"gthumb --import-photos /path/to/images".

We'll probably want to tweak the UI to allow the selection of particular 
folders. We might want to have 2 menu entries: "Import from all attached 
cameras" and "Import from specific folder" (with a folder chooser).

Anyway, patches welcome!

Oh, read here for the pros and cons of using gvfs in the importer:
