* 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. svn path=/trunk/; revision=1562
