2149 – Auto variables loose the keyword "auto" in di files generated with -H option.

When generating an interface file using the -H option for a class like this
 class Point {
	
	 auto x = 10;
 	 uint y = 20;
	
 }
The generated interface file misses the "auto" keyword:
 // D import file generated from 'point.d'
 class Point
 {
 x = 10;
 uint y = 20;
 }
This causes compilation errors when using this interface file:
 no identifier for declarator x
 Error: identifier 'x' is not defined
 Error: x is used as a type
 variable voids have no value

Fixed in D versions 2.015 & 1.031.
