0.6.1.0: Some bug fixes

A new version is available on the default branch.

-Fixed a bug where the game would stop responding after task switching in windowed mode, or would show a black screen with only the mouse cursor active when alt-tabbing in fullscreen mode. (Please note that task switching during the save process can still cause a freeze/not responding) -Corrected an issue where the characters would sometimes haul tools like clay jars that were being used for collecting sap. -Fixed a bug where the "NEW RUN" button on the Missions panel would not accept a mouse click. -Fixed a bug where sometimes achieving the required ratings would not trigger the win condition on 'Making Headway'.
