Slipperiness setting for blocks

Status
Fixed
Issue description

This option would make it possible to create slippery blocks such as ice; the default slipperiness value is 0.6F.

It can be set by adding

.slipperiness(0.6F) //1.14.4

this.slipperiness = 0.6F; //1.12.2

to the constructor

Issue comments

Does it mean that if you set the Slipperiness to a value < 1 like 0.6 the Player gets slower but if you set it higher then 1 would the Player accelerate forever?

Actual the inverse works, ice has bigger slipperiness which makes it move a bit slower, but stops later and vice versa.

It should be called momentum amount but they call it slipperiness.
