German OOB 16: minor corrections

[DRG]

The SdKfz.6/3 will go in, the Stalinez is now in ( with a revised Icon ) and the C7 stays in. If we finally run out of space that's the way it goes. There is little point in hording unitslots as there is little left to add to that OOB that doesn't fall into the same category as the SdKfz.6/3 and once the OOB's full the question isn't " should this be added" but what should be removed to make room for the next unit someone thinks needs to be included.
