Removed some code which got in the way of testing properly.

        * widgets/test-minicard.c: Removed some code which got in the way
        of testing properly.

        * widgets/e-minicard-label.c (e_minicard_label_realize): Made the
        field text item editable.

        * widgets/Makefile.am: Added e-text-event-process*.[ch].

        * widgets/e-text.c, widgets/e-text.h: Changed these to support
        editing.

        * widgets/e-text-event-processor.c,
        widgets/e-text-event-processor.h,
        widgets/e-text-event-processor-types.h,
        widgets/e-text-event-processor-emacs-like.c,
        widgets/e-text-event-processor-emacs-like.h: These are a new pair
        of classes which handle all events from the text item and convert
        them into commands.
