Log Message:
Update "bidwatcher" to version 1.3.16. Changes since version 1.3.15:
- Parse eBay pages properly again
- A parsing error leading to a segmentation fault is fixed (patch
  from Klaus Singvogel)
- Get the snipe key 60 seconds before sniping because this key becomes
  stale.
- Snipes do not try to get a snipe key at startup or setup.
- Set the proxy during startup.  Otherwise a "Network error" is issued
  at startup behind a proxy.
- Workaround a bug with german umlauts and other ascii > 127 in the
  details windows. They are simply removed.
- Recognize shifting end times of auctions.
- User listings:
  - The auction-id was read as "unsigned long" (4 Byte) instead of
    "unsigned long long" (8 Byte). Due to that truncation some
     auction-ids were not handled correctly.
  - Ebay places linebreaks at the worst places in its pages: the
    parser did not remove them all. So the auction id was not
    found.
- Obtain snipe-key just when necessary, not earlier.
- New feature: Snipe groups
