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. svn path=/trunk/; revision=1553
