The bottom formatting toolbar now shows the formatting options
previously located in the main toolbar as a menu entry (bold,
italic, ...). In addition alignment options and selection of fonts
and sizes have been added.

Bottom formatting toolbar is not shown by default - it enables when
hitting the icon in main toolbar. Also soft keyboard and formatting
toolbar should not be shown at the same time.
