[KimDaBa] EXIF support added

[Jesper K. Pedersen]

OK, I've added EXIF support for KimDaBa now. It will read date, rotating
and comment out of the EXIF file. It would be nice including all the other
EXIF information in KimDaBa, but that has to wait for a later version ;-)

I don't have any images with rotation information in, so someone who do
have such an image, please check that KimDaBa gets it right. Please send me
an email telling me about it (both success and failure). I'd also be happy
to get some images with this information in, so please also send me such images.

A new package is now available at http://ktown.kde.org/kimdaba/snapshots/

Kind Regards
Jesper.
