Update 0.43

I had some health issues, so this update took way longer than expected. I'm much better now though.

The main thing in this update is the new boss fight mode.

Also, I switched to DirectX 9 ex, which might cause issues on some systems, so let me know if there are any weird bugs or problems starting the game.

Change log:

• Added initial boss fight game mode.

• Switched to DirectX 9 ex, requires Windows Vista or newer.

• Player now collides with static objects.

• Gatherers now ignore mana that is in the castle limits.

• Fixed a mouse input bug.

• Using a different font (more localization-friendly).

• Switched to Visual C 2017.

• Added IK animation system.

• Added voxel-based model generation system.

• Added a bunch of developer tools.
