OBMenuBarWindow 1.1.0

This release adds two properties to allow you to alter the appearance of the window's title bar:

• titleBarHeight - the height of the title bar
• arrowSize - the size of the arrow that points to the menu bar icon

(Replaces the OBMenuBarWindowTitleBarHeight, OBMenuBarWindowArrowWidth and OBMenuBarWindowArrowHeight constants.)

It also adds an OBMenuBarWindowDelegate protocol to get notified when the window attaches to or detaches from the menu bar.
