Button: Simplified the selector for native input style.
Fieldcontain: Label margin bottom inside popups should match the default we set in core.css.
Textarea: Make mini size work when class ui-mini is on the container. Adjusted margin for mini textarea.
Changed font-size 16px to 1em or removed the setting if not really needed.
Core: Made buttons in toolbars default to mini and inline. Adjusted ui-btn-left/right offset values.
Navbar: No class ui-mini for navbars but only set mini font-size.
Demos: Changed a class in custom navbar icons example.
Core: This was only needed because the loader and buttons with icons both got the ui-icon class, but that is gone.
