Small Improvements - Mouse Control & Engi Unlock Achievement

Just a small patch to make some important improvement.

Mouse control had a weird interaction with the Confusion mechanics, I tried a new approache which should make it much more manageable, the paddle will now mirror the mouse movement. I also added a marker during the confusion that shows where the paddle is moving to. Also remember you can slow down the bar movespeed by holding MB4. Hopefully this helps, the Mouse Control option is still considered experimental, more improvements will be made depending on the feedback.

Also as many of you have noticed the next hero will be the Engineer! More info on him later, but for now his unlock condition is now revealed: Destroy 25 bricks in a 5 seconds interval. The unlock is voluntarily easy to accomplish, the hero is meant to be fun and accessible for beginners. He needs a bit more work so he won't be playable until next week, but it is already possible to complete the unlock and get the achievement to be able to play him as soon as his update is out.

Here's the complete patch note :
