A few fixes on SqueakSource.

Polymorph-Widgets-gvc.24

Polymorph-Tools-Diff-gvc.24

Notably:

Table layout of submorphs with #shrinkWrap attributes.

Themeing of menu item text colours to help Hilaire in his Sugar theme efforts. ThemeSettings integration left for another time...

Wrong "sides" for "compare to current" when using diff tools in change sets (versions browser etc.).

Prevention of window dragging from submorphs promoted from StandardWindow to SystemWindow (deals with oddities when click-dragging from submorphs... offset would be wrong and window "jumps").

Wrong colours for faded background windows in Watery themes.

Fix colours in W2K theme (requires class-side reinitialisation of defaultSettings. Do "UIThemeW2K defaultSettings: nil" before changing theme).

Toolbars now Panel-based to adapt to pane colour.

DockingBar based menus now deal with mouseFocus correctly.
