Styling HBox/VBox/GridPane child properties (hgrow, margin, columnIndex, etc)

[John Hendrikx]

Thanks,

I may need some help with the transition part when the time arrives. In
CssStyleHelper these parent defined properties are treated no different
from any other properties, but I think some of the transition logic is
part of the properties themselves and I didn't implement that so far.

How I've implemented them currently is with just-in-time properties that
only implement StyleableProperty (so it's not a full property that could
be bound).  The actual storage is in the properties map associated with
all Nodes.

I'll see if I can work this up as a PR over the weekend.  It works
already, but needs some polishing and perhaps some optimization as its
part of CSS code.
