        * widgets/e-minicard.c, widgets/e-minicard.h: Added a resize
        signal for when the card changes height.  Made it so that when you
        press tab inside of a field, it goes to the next field.

        * widgets/e-minicard-label.c, widgets/e-minicard-label.h: Added a
        resize signal for when the label changes height.

        * widgets/e-text.c, widgets/e-text.h: Added a resize signal for
        multiple lines.  Added scrolling based on cursor position.

        * widgets/Makefile.am: Removed an extraneous build target.
