Custom debug display

[ncannasse]

Allow to define a static per class, which can customize the way the debugger displays values.
For example:

class Point {
     static var __debug_repr = "[$x,$y]";
     public var x : Float;
     public var y : Float;
}

Why as a var, rather than a function that returns a String? The latter seems more flexible.

eval-debugger simply uses toString().

It's not very easy to call the VM... would require making all threads pause and create another thread that executes the code...
