Property Observable: true's event not accessible in strict mode

Also, it's worth mentioning that I can't find a way to modify the setter access separate from the getter. It'd be nice if automatic properties used a more C#-style syntax, like

public MyProperty as string:
get
protected set

or whatnot. Then Observable, instead of being a modifier of Property, could be an attribute that applies some code after the setter finishes. Be a whole lot more natural.

Actually You can add ProtectedSetter: true to the AST attribute

I also think the C# syntax for automatic properties is more elegant, and indeed observable could be a AST attribute applicable on property nodes.
I guess we could implement that with the new parser (not sure it's worth to do the changes on the parser now) => BOO-1198

It would be a beautiful syntax, nicer than C#'s because it lacks all the semicolons. Also less of a change when someone decides to add a real implementation for the property..
