58ab76269c LibJS: Add all the Error subclasses 
This patch adds instance, constructor and prototype classes for:

    - EvalError
    - InternalError
    - RangeError
    - ReferenceError
    - SyntaxError
    - TypeError
    - URIError

Enumerator macros are used to reduce the amount of typing. :^)

343e224aa8 LibJS: Implement basic exception throwing 
You can now throw exceptions by calling Interpreter::throw_exception().
Anyone who calls ASTNode::execute() needs to check afterwards if the
Interpreter now has an exception(), and if so, stop what they're doing
and simply return.

When catching an exception, we'll first execute the CatchClause node
if present. After that, we'll execute the finalizer block if present.

This is unlikely to be completely correct, but it's a start! :^)
