Fix showfoto usability.

This resolves issue #50.

The problem seems to be a known issue already addressed by the original
authors. This is an extract from the 'ChangeLog' file that best
describes the issue:
```
Fix a linking problem with showfoto, image plugins and
--enable-gcc-hidden-visibility:
All image plugins link to libdigikam.so.
The showfoto executable however does not link to this lib, but
statically links the relevant parts.
With visibility hidden, now the linker obviously cannot see the
already linked DImgInterface class,
and there would be two different static variables for
DImgInterface::instance(). One with the loaded
image, the other (from the image plugins) with a null image.
```
Linking against libdigikam.so instead of including the libraries in a
static way solves the issue.
