A quick & dirty OS4 port of Stefan Ruppert's binary.datatype
(http://aminet.net/package/util/dtype/binarydt_39.11).

Advantages/disadvantages over AROS binary.datatype:
 + uses the complete window for display
 + a real base datatype and not a text.datatype subclass (shouldn't use as much
memory)
 - mark/copy doesn't work at all
 - find doesn't work at all either

The disadvantages are not so severe though, in my opinion, considering these
don't work that well either in the AROS datatype...
