c0365fd52aThis patch makes the binding templates ObjectTemplates, since we
don't actually need the constructor function. This also avoids
setting the properties on prototype, and instead initializes them
directly on the object template.
Previously the initialization was similar to:
```
function Binding() {}
Binding.prototype.property = ...;
module.exports = new Binding;
```
Now it's similar to:
```
module.exports = { property: ... };
```
