WPN SNG Results

[joeleong]

Wondering how hard it would be add automated SNG results for WPN.
Seems pretty easy to figure out when people are eliminated in hand actions (isSng and starting stack == chips lost).

I'd be happy to try and submit a PR, just not sure the best modifications to make.
Seems like the easiest thing would be to just directly update tourney results from WinningToFpdb.py, but it seems like I'd have to modify the relevant hand class to store placing info (where it usually seems like this info is only updated through summaries? even for other sites?) and add a function in Database.py to modify the relevant rows.

Thoughts?
