Allow to define a default attribute within a type that can then be used within assignments.

Needs to extend DLInstance to have a default attribute, add an annotation @default and extend the assignment handling in parser.

something like:

type H1 extends HTMLElement 
{
	String text @default: "";
}

Div myContent {
	H1 heading : "Welcome"; // <- Creates a new instance of H1 and assigns its text
	P description : "Little text \nwith multiple lines"; // <- Creates a new instance of P and assigns its text
}
