Support for maintaining multiple variables and fields on a line

[KathleenDollard]

This is legal in C#

public class A { private string A, B, C;

public void Foo() { int X, Y, Z; } }

which is semantically the same as putting them on separate lines.

RoslynDom loads these as though they were on separate lines. This is important in analysis that needs all the variables in the class and treats variables created with either approach identically. Currently, the syntax tree RoslynDom recreates places these on separate lines.

However, RoslynDom could roundtrip the code by recreating the syntax for the combined declaration using some grouping ID.

I anticipate doing this sometime when I am bored, if this is important to you, let me know.
