Multiple PoW updates

- fixes "fast python" (multiprocessing) PoW
- python PoW (both slow and fast) interruptible on *NIX
- signal handler should handle multiple processes and threads correctly
(only tested on Linux)
- popul window asking whether to interrupt PoW when quitting QT GUI
- PoW status in "sent" folder fixes and now also displays broadcast
status which didn't exist before
- Fixes #894
