More options for empty lines between types

[gene-pavlovsky]

The emptyLines.betweenTypes setting gives all-or-nothing power.

It would be nice if there was some flexibility (e.g. wrapping options offer a lot of customization via rules/conditions, sameLine options allow moderate customization since they offer separate settings for non-block bodies of various control structures). Same can be said in general for lineEnds, whitespace and some other emptyLines options.

Sample desired Output

typedef Point2D = {x: Int, y:Int}
typedef Point3D = {x: Int, y:Int, z:Int}

class A {
    ...
}

class B {
    ...
}
