Proposed UI changes in 1.3

[Christian Neumair <chris gnome-de org>]

Here is the list of what I plan to enforce for Gnumeric >1.2 when it
comes to UI:

- Unify Widget Naming Conventions
current situation: all kinds of notations used (e.g. "window56",
"button43")
objective: all widget's names should be some-function-widgettype (e.g.
"input-label", "input-entry", "ok-button", "scenario-dialog")

- Clean Up UI
current situation: HIG not completely enforced, many spacings look ugly
since they aren't consistent, instant apply should be used where
possible
objective: all dialogs HIG-compliant, consistent spacing, instant apply
where possible

- Add ATK relations
current situation: rudimentary available
objective: all UI components ATK-ified

 Chris
