Localization update!

You asked for it, here it is. The game is now available in the following languages:

• Simplified Chinese

• Japanese

• German

• Brazilian Portugese

• French

I've also fixed a couple bugs:

• Fixed bug where lumberjacks would cut sapling that is not the lowest base tier.

• Introduced a save file backup to reduce chances of save file corruption.

• Having a savefile corruption now enables a special tool to give progression back.

Finally, I had to remove the demo because it was complicated to keep two versions of the game up to date. Sorry about that.
