This adds a new object type "Data Table", with all the object
identifiers and converters of properties.
The data table is now shown in the drop-down of chart elements.
A properties dialog was added, which allows to change properties
of a data table. This contains the area, line and font tab pages
and a new tab page specific for data tables, to change if the
horiz. or vert. borders, key or the outline should be show.
