get_component() Utility Function

[Archmonger]

Make a utility that returns a component given a certain path, if it has been registered.
This already exists to some degree within IDOM (for the templatetag), but needs some massaging to be a public tool.

I would love to work on this as I think it will be super helpful. If somebody could push me in the right direction, I could give a shot.

Hey @brdhunga

This function would essentially be the inverse of our register function.
