Plugin: try to automatically load an eventual plugin's gui, named  mypluginname_gui.
Note : A plugin GUI must be compiled in another .so, not to link the "pure" plugin library with Qt (so the plugin can be used with another Software that does not use Qt or another version...)

Plugin: do not write a warning message if the plugin does not have a gui library.

Image: moving Qt-based widgets into another plugin named "image_gui" such as the image plugin does not depend on Qt.
Warning: the separation is only effective for CMake. The QMake version, still compiles everything in only one plugin.
