Some improvements

Hola!

I added some small improvements to eog that make my life easier.

The things I did are:

1. Added a new menu entry that allows to copy the currently viewed 
image's path to the clipboard. I am using this to make it easier to send 
images over IM for example so I don't have to search everytime for the 
picture path and the exact filename (even worse with images from a 
digital camera where the names contain a lot of numbers ...)

2. Added a new menu entry that allows to toggle between real size and 
fitted one, so I can switch with one key shortcut between the two.

3. When in normal view mode, use ESC key to quit eog (Sorry for that 
fast quitting, but that's because I am used to it from other tools).

As said, these are just very small things, but I think they could be 
useful for everybody using eog.

If you want I can submit a patch, but as I am using Ubuntu Hardy I made 
the changes against eog 2.22.2, so I would also submit a patch against 
that version?
Would that be one patch or 3, one for every change?
