Replace Math with FastMath for improved performance.

Browse Source 
FastMath is a drop in replacement for the native Java math class with improved performance and fall backs to the native Java math class if necessary.

https://commons.apache.org/proper/commons-math/javadocs/api-3.3/org/apache/commons/math3/util/FastMath.html

This requires further testing and might cause chunk borders due the FastMath giving slightly different results than the native Java math class.

I also added .idea/Terra.iml to the .gitignore
