Feature/md-autocomplete

[zAPFy]

This is a very basic implementation.

It uses MdInput with a different container, is this a good way of implementing it?

Problems:

• Overflow hidden on parent element.

-The only way to get around this would be to insert the autocomplete at document root, but that would cause a whole bunch of other problems.

• Inserting the autocomplete data as an Input.

-For some reason I cant get this to work.

Todo:

• Arrow key navigation.
• Input validation. Only allow autcomplete data as valid input value.

I'll keep working on this for a bit.
Any feedback/input/sollutions are more than welcome.

@axal90 sorry that this got all busted up in the 0.4.1 changes. I think you could do this pretty well with the Overlay system in Material2/core right now. Do you plan to try a new PR against the new setup?

@justindujardin No problem. I stopped all work on it expecting some rework. It should be easy and I'll get on it as soon as I have time. :)
