Implement copy file from PictureViewer2

Add an action to PictureViewer2 for copying the current pic to another
directory.

When I tried to add the QAction to the context menu, I realized that I
chose the variable names picView and picViewer in shemov.cpp very
poorly. Took some time to sift though it. Eventually I shifted some code
around to make it more readable. While at it I replaced the individual
separators with createSeparator(). Other than adding the Copy To action
no functional changes.
