Achievements are now working again in SS Steam Edition

Seems I broke the achievements in v1.1.3, so I fixed them. You can also now check for achievements you should have had but didn't receive using a new option in the game's settings. This also works for importing saves over from other versions, but most progress doesn't carry over into NG+ so you would want to use like an epilogue save game instead.

Sorry for the inconvenience!
