Make launchtaskbar plugin more closely mimic launchbar and taskbar.

When launchtaskbar applet is created as launchbar (or taskbar) it should not
allow it's mode switching and also configuration window title should show
appropriate text. This way it completely mimics simpler plugins.
Use libfm-gtk APIs for "Add to desktop" context menu item on Menu plugin item.

The libfm-gtk already have everything to create shortcut on desktop so this
should be done much simpler than own implementation and copying the file.
