Fix bug with "isWinner"
- "isWinner" was reporting false regardless of outcome. Adakite provided
a possible fix for this in the following pull request for OpenBW's BWAPI
fork: https://github.com/OpenBW/bwapi/pull/11.
However, ZergGreenOne noticed "update()" was not being called after
the game ended in BWAPI4J's BWAPILauncher. Both fixes work, but we will
go with ZergGreenOne's.
- Much thanks to github:ZerGreenOne for finding and reporting this bug!
