Changed the Last Invoice/ Last Quote information in the sales document pages so that they are more readable

Changed the "Last Invoice / Last Quote" information in the sales document pages so that they are more readable.

Furthermore the information takes less space now.

The change of the presentation of "Last Invoice / Last Quote" information led also to a change of the "Special Price" and "Special Discount" Information as this was presented in the same structure as "Last Invoice / Last Quote".

The special information is now not shown in a label below the repeater. It has been replaced by a colored highlighting of the values "Unit Price per PU" and "Line Discount %". Addtionally when the Price and/ or Discount has a special value, the column headline changes dynamically.

This type of visualization also makes it possible to recognize easily all lines which have a special price and/ or discount within a Sales Document.
