Allow mdGridList to flex to fit the available area

[Splaktar]

This comes from the discussion here: https://groups.google.com/forum/#!topic/ngmaterial/Rq22sOFJOco

I wrote up a quick and dirty prototype for how it should behave here:

The basic idea is to allow the mdGridList to fill up the available space, but not exceed it. I set the md-row-height ratio dynamically to make this happen.

I love that this idea was vetted on the forum. Thanks for providing prototypes! 👍

I thought

 md-row-height="fit"

was serving this purpose.
It does not appear to work in v0.9.0-rc1-master (worked like a charm in 0.8.3).

Is there a particular design reason why md-row-height='fit' isn't working anymore?

The "fit" option is still listed in their help topics too: Directives for mdGridList
