Add Barberpole.{h.cpp} from BarberPole1.0.zip

Got the file from https://pulkomandy.tk/~beosarchive/.

Changes to that:

* Renamed BarberPole.cc -> BarberPole.cpp..
* Removed include for "Colors.h", no idea where that comes from
  and doesn't seems actually needed.
* Added default value for the flag constructor parameter.
  Not sure if the value is correct, but prevents compile errors
  for now.

+
+BarberPole is a little class, that shows this little spinning barber pole, you probably know from Net+ or the Tracker.
+
+This is V1.0 and should compile on both x86 and PPC, although I currently haven't tested it on PPC. If you want to set the color of the pole, do it by using 
+
+myBarberPol->SetHighColor(...) 
+	and 
+myBarberPole->SetLowColor(...)
+
+BarberPole is Freeware. If you made any changes, please report it to me, so I could update it.
