v2: Button alignment in MessageBox is no longer centered

[fergusonr]

2.0.0-pre.1491 MessageBox buttons are aligned to the right. They were previously centred.

If this is a v2 style change, then perhaps we should have a Query() method signature with a ButtonAlignment parameter

MessageBox.Query(50, 7, "Quit?", "Are you sure you want to quit?", 0, "Yes", "No");

With POS.Align I was experimenting with layouts. I forgot I left this in.

For v2 I want to do two things:

Change the defaults from v1 to make the look and feel distinct.

Make it configurable (MB and Dialog can/should be different).

And I mean configurable via CM. Not api.

Great thanks.
