[Foldit] Reflow Title based on screen width.
StandaloneApplication can now tell the TitlePanel how much size it has, and it figures out how to fit into that size.
* Also resize the title bar of the objective panel to match the title bar size. (The objective panel itself stays the same size, but that doesn't conflict with anything.
* Add tooltips for the full title, when truncating the title.
* Add code to adjust the font size down when truncating the title, to try to keep more of the title visible.
The setup should be extendable for other GUI elements we want to resize/reflow based on screen size.
