wrote EOG plugin: exif display

Hello,

     I wrote a new plugin for EOG: exif display (in C).

     It displays the most important EXIF info in the sidebar and 
optionally in the status bar and shows in the sidebar per-channel or RGB 
histogram for the current picture.

     I put a screenshot there:
http://www2.arnes.si/~shvali/exif-display-screenshot.png

     And the source code is there:
http://www2.arnes.si/~shvali/exif-display.zip

     I started based on the directory structure and the autoconf stuff 
of git.gnome.org/eog-plugins

     To build it you can just copy the exif-display folder under the 
plugins/ folder in that GIT tree (next to "champlain, fit-to-width etc).

     I changed the configure.ac, I put the changes at the bottom of this 
mail.

     I wonder if you'd be interested to take this plugin in that git 
repository or somewhere else so that also others could use it. I think 
it's useful for people who care about digital photography, and it would 
get a much wider audience if it's in the main EOG repository.

     There are probably some problems with the code also, I'm interested 
if you notice any.

     Any feedback welcome!
