New shape mode "Pluses", start of the ui update, bug fixes, fast rotate button, physics changes - Version 1.1

Pluses
A + shaped mode that allows some diagonal stacking if you are careful, but it is easy to make mistakes that ruin your run. Sometimes the "x" orientation allows for better balancing too. These haven't been added to random yet and I'll be seeing testing them a bit more over the coming days.

I have started on improving the visuals, creating new ui assets, and scrolling background shapes that are chosen differently based on the mode you are playing, and updating color schemes a bit. In the bottom left corner there is now a version number, and this should also tell you when your client is out of date now with a warning message (it checks with a server).

Fast Rotation

The preview display toggle has been moved to middle mouse button, and right click now rotates the shape you are holding, and the amount it rotates is different per shape with what I thought would be most useful for that shape. For example squares rotate 45 degrees since 90 degrees would leave it the same, triangles rotate 360/6 degrees.

Suika Classic

Suika classic has been updated to have less depenetration force, so less launching but still a bit. Masses of the shapes I were also adjusted with this. There's been a lot of feedback about the launching and it may have been a bit excessive, I don't have a great way of comparing this to the original but hopefully it's closer now.

And lastly, Suika++ has been renamed to Speed Suika to give players a better idea of what it is before clicking on it

I have submitted a steam page for review so expect that to be available soon. Thanks to everyone for playing
