Initial Check in of the Eye Of Zilla. This ImageViewer features

Image Infos, EXIF, Jpeg,Png,Gif support. It supports scaled loading
of Jpegs. an smart image cache....

GUI needs some work and we need to find a bug in QCOP as well.

TODO:
Add Image Service for example Mailer
Add ImageCanvas/Zoomer/Display
