Cleanup some unused variables

* Make the app progress indicator only have the indeterminate state
  when the taskbar indicator is used (causes an uused variable warning
  on wx<3.1)
* Remove unused dry run variable in pcb_netlist.h
* Remove unused forceDropAnnotations from the paste special dialog
  since the dialog only controls keeping them.
