WARNING: *get mxct
 

With v418 prostar changes the behaviour of returning the value of mxct (max defined cell type) and returns the correct value now.

So "mxct - 2" is no longer the cell type of the WALL shells !!!

Now there are two ways of selecting wall shells:

1) mxct - 1
2) cset news name WALL -> this works as long as no other cells have the same name
