Whooray! 

Just finished logic for the air balloon physics!

Now the altitude is dependent from several factors, but in future player will be able to control it.

By increasing / decreasing volume of converted power to "heated" volume is a factor wich is important to reach target height. This is now most important factor, because with the hight, the "heated" volume will be decrease faster.

Max volume (which also effect of how fast altitude can be reached) is about how much volume can be "heated". By selecting different types of air balloon the player will be able to change that param.

Power usage - is factor of how much power will be used per second to "heat" the volume.

And as the result - the object now is moving smoothly and falling smoothly when the "heated" volume and power is gone.
