window dimensions should be saved immediately, not only when closing a window

[Avi Romanoff]

pantheon-terminal opens new windows with the same width and height of the last saved dimensions in GSettings. However, those values are only updated after a terminal window closes. That's bad behavior -- the GSettings dimensions should be the dimensions of the last-resized window, whether or not its been closed yet or not.

The problem, as discussed, is this:

1. Last window size was something really big
2. Resize to a smaller window
3. Open a new terminal window

Expectation:
4. New terminal window is small

Reality
5. New terminal window is really big

I've noticed this as well. Is there any reason we can't update GSettings after a resize? Perhaps with a delay after they stop resizing of a second or so we don't spam GSettings if someone is actively resizing a window.
