Interface overload/new signature inconsistency

[dsherret]

Interface new signatures and methods are different than functions and class methods/constructors. The others have an implementation signature, but interfaces don't for constructors and methods.

What should be done here?

Options:

1. This could be similar to Method and function signatures in ambient context - Generated implementation signature #218.
2. Only have signatures.

I'm leaning towards the second option.

Not doing. Focusing dev effort on ts-simple-ast. This library sorts out this issue.
