  [ftinspect] Support drag & drop to open font files.
  
  A possible issue is that no checking is performed to ensure the dropped files
  are real font files.
  
  * src/ftinspect/maingui.cpp, src/ftinspect/maingui.hpp: Use custom
  `dragEnterEvent` and `dropEvent` to accept drop operations. Dropping was set
  to unaccepted for `glyphView_` to let the event pass down to `MainGUI`.
