Migration from v15 to v16

The big different between v15 and v16 is in component internal prototypes. Changes are described here:

component.set([path], value, [type]) // v15
component.set(value, [type]); // v16

component.inc([path], value, [type]); // v15
component.inc(value, [type]); // v16

component.extend([path], value, [type]; // v15
component.extend(value, [type]); // v16

component.rewrite([path], value, [type]); // v15
component.rewrite(value, [type]); // v16
