Handle the grab and ungrab command instead of doing focus by hand. This

2000-01-28  Christopher James Lahey  <clahey@helixcode.com>

        * widgets/e-text.c (e_text_command): Handle the grab and ungrab
        command instead of doing focus by hand.  This fixes a problem
        related to the scroll wheel.
        (e_text_command): Reset the blink timer in many more command
        situations so that the cursor blinks less when you're interacting
        with it.

        * widgets/e-text-event-processor-emacs-like.c: Send the grab focus
        command when starting a selection and the ungrab focus command
        when ending it.

        * widgets/e-text-event-processor-types.h: Added grab command type
        so that the event processor can tell the widget to grab the focus.

        * widgets/e-reflow.c: Redefined all sizes using #defines so that
        they can be tweaked later.  Added scroll wheel handling and set up
        adjustment increments so that the scroll bars will work correctly.

        * widgets/e-minicard.h: Added minicard focus type enum.  This
        doesn't mean anything yet, but it will later be used to say which
        direction the focus is coming from (below for shift-tab, above for
        tab.)
