BWindow needs a LayoutChanged() hook method

Here's a link to the relevant thread on the ml: ​http://www.freelists.org/post/haiku-commits/r42106-haikutrunksrcpreferencestime

Looking at the source for BView, I think a good place to call this hook would be once the view, and all of its children have finished doing layout. This way, we are actually providing functionality beyond what you can get by overriding DoLayout(). I don't think this hook fits in BWindow, since it delegates drawing/layout to views and layouts; it doesn't do any of this work itself.

We currently have 5 remaining BView virtual methods, so I see no problem with adding this method. If anyone disagrees, reply here, if nobody replies to the contrary soon, I'll implement this (should take about 2 seconds).

I'll push this to git.haiku-os.org once the svn -> git migration is complete. In the mean time, anyone who wants is free to review my fix at the link above.

Replying to scottmc:

Haha yeah. Maybe I should have said _after_ the migration is complete ;) I need to do a full build on my little laptop to perform integration testing of this and other changes, which I've been putting off since it is pretty slow. This change could probably be pushed safely on its own, but it's in between a bunch of other layout changes.
