Adds NSWorkspace.RevealFilesInFinder
Window smooth resize accounts for toolbar height if one is available, otherwise use titlebar height.
Removed NSWindow.SmoothResize method, since it's basically a window extension.
Added named constants to window extensions for the SmoothResize method.
Calculate window content and titlebar/toolbar height rather than using constants.
Built Target Cocoa
Grabbed my old copy of the 'Carbon Declares Library' and added the carbon version of smooth resize, might also potentially be able to work under Windows, but I'm unable to test this.

NSWorkspace.RevealFileURLs checks of function availability before invoking it to avoid crash on pre-10.6 systems.
Adds NSWorkspace.RevealFiles(f() as FolderItem) because we also have a SelectFile that takes a FolderItem.
