Ability to yield in the component.

[Kilowhisky]

This adds the ability to yield a block inside the component input-group that way additional input-group-addons can be specified at the beginning of the input.

This is useful for extending the capabilities of the component without overriding the hbs file.

Example.

What if someone else needs to add something on the right side as opposed to the left side?

Until named yield blocks (emberjs/rfcs#226) are a thing there is nothing that can be done about it.

Anyways i decided not to use this plugin so use it or close it.
