Ancestors: Morphic-mt.851

Convenient messages added to morphs to check for current mouse or keyboard focus. Could be used, for example, to change visual appearnce to indicate that focus. Does not happen yet (except for the blinking text cursor). (in conjunction with #keyboardFocusChange:).

Note: We should get rid of #hasFocus because only hands now the exact information. For multiple hands, such cached information in the morph may not valid anyway.
