issue1413: Only show unknown sediment loads of selected unit type.
Therefore, adjusted the factory to take the units name. Unfortunately,
names in db do not match values of data items. Thus do manual replacing.
In Facet and Calculate, take the chosen unit via access and to the string
replacement.
In Facet, do not transform data (we assume it comes in unit as labeled in
the db), and removed the possibility of m3/a-data of unknown yields in a
t/a diagram and vice versa.
