v0.3.0

• Change data-target to data-targets for the @targets decorator.

This is a breaking change, whereas the old style decorators did the following:

Decorator	Equivalent Native Method	Selector	Returns
@target	querySelector	data-target="*"	Element
@targets	querySelectorAll	data-target="*"	Array

The breaking change is that @target now selects for data-targets (with an s) like so:

Decorator	Equivalent Native Method	Selector	Returns
@target	querySelector	data-target="*"	Element
@targets	querySelectorAll	data-targets="*"	Array
