Italian language support

Outcore can now be played in Italian! Special thanks to Jessica Amoruso, Federica Carboni, Federica Crepaz & Martina Previtera from PrismaLoc for providing the translations.

The cursor will now be locked inside the main screen while aiming a star using a mouse.

Added another bullet point to this bullet point list to make it seem like a lot more was done for this update.
