Gives objects a meaningful name

 - LithophaneImages will be named after the image file on import
 - Create Box command will use the Label of the LithophaneImage and append
   _Box to it
 - Create Solid command will use the Label of the mesh and appends _Solid
   to it
 - Show Pointcloud command will use the Label of the LithophaneImage and
   append _PointCloud to it

fixes #12

 Depending on the image and your machine, it might take a while for the import to finish. On my 8 years old Intel i7-2670QM it takes about 8 seconds to import the windmill image (814x1000 pixels). **FreeCAD might be unresponsive during the import**.
 
-The name of the imported image object is hardcoded to `LithophaneImage` right now. So when importing more than one image it might be hard to distinguish the images from each other. See https://github.com/furti/FreeCAD-Lithophane/issues/12

 **The pixel data whil be computed every time you recompute the image object!** This can happen when you change some settings of the image or force a recompute of the whole document.
 For performance reasons the calculated point cloud is stored inside the FreeCAD file. So your files can get pretty big real fast when you import big images.
