Done.

+    RuntimeEnabled=BudgetService
+] partial interface Navigator {
+    [CallWith=ScriptState] Promise<double> getCost(ActionType actionType);
+    [CallWith=ScriptState, RaisesException] Promise<double> getBudget();
+    [CallWith=ScriptState, RaisesException] Promise<FrozenArray<BudgetChunk>> getBudgetDetails();

Why do you annotate getBudget() and getBudgetDetails() with RaisesException when
they don't actually raise an exception? :)

[harkness, 2016/07/20 09:41:48]

I assumed that they would eventually, an in fact they do now!
