improve dump functions in core about maashaack HOT 1 OPEN

even better, let's use a bit of reflection fun ;)

for ex:

var r:Rectangle = new Rectangle( 0, 1, 2, 3 );

var _class:XML = describeType( Rectangle );
----
<type name="flash.geom::Rectangle" base="Class" isDynamic="true" isFinal="true" 
isStatic="true">
  <extendsClass type="Class"/>
  <extendsClass type="Object"/>
  <accessor name="prototype" access="readonly" type="*" declaredBy="Class"/>
  <factory type="flash.geom::Rectangle">
    <extendsClass type="Object"/>
    <constructor>
      <parameter index="1" type="Number" optional="true"/>
      <parameter index="2" type="Number" optional="true"/>
      <parameter index="3" type="Number" optional="true"/>
      <parameter index="4" type="Number" optional="true"/>
    </constructor>
    <variable name="x" type="Number"/>
    <variable name="y" type="Number"/>
    <variable name="width" type="Number"/>
    <variable name="height" type="Number"/>
...

var _class:XML = describeType( r );

eg.
we can find out the class name, the number of args in the ctor, if they are 
optional or not, etc.
