HotFix 1.0.5+updated engine

HotFix 1.0.5 and updated engine version.

1)

As it became known: Unity has a serious vulnerability, so we had to update to the latest version.

2) Fixed the thundercloud: on the third island, for some reason, after the first “cloud dispersion effect” — let's call it that — VFX did not want to work again. But the rain worked fine repeatedly.

It turned out that the rain was Constant and the dissipation was Burst single — basically what I needed, but it didn't work the way I wanted it to.

So I replaced Burst single with Periodic Burst, which didn't really help until I created a Bool parameter for it (namely Delay) Bool, which is read by this parameter as a delay in calling the next effect until the nearest Bool, rather than a numerical value as default.

3)

I fixed the back sprites (island, cracker, etc.) by setting their display sorting parameters (I didn't use this at all).

4)

I think I figured it out and fixed the disappearance of the birds; it seems that the problem was also in the render layers.

5) PAUSE NOW STOPS TIME. Now it is impossible to pause and avoid falling into the water.

I broke a lot of things and fixed them back, and made all sorts of minor corrections.
