Redesigned initial dialog

[Armin Burgmeier <armin arbur net>]

I just committed a first version of a redesigned initial dialog to Glom
trunk. There is a screenshot at [1]. It is currently very similar to
Murray's proposal [2].

I think that it would be better, UI-wise, to only use one treeview for
both types of actions. Normally, you are only interested in either
opening an existing document or a new document (but not both), so you
need only one of the views anyway. But when you resize the dialog, to
view more items at once, half the space is wasted for the other
treeview. If all actions were in a single treeview, then you would only
expand the branch you are interested in, giving all extra space to those
items.

The actions already make clear enough whether they open an existing
document or create new one, IMHO.

Opinions?
