Fine zero offset and base offset

Zero point shift
This function refers to the offset in the screen form "Settable work offset" and "Base work
offset". Another column for the fine offset is inserted alongside the column for entering the
offsets.
The inputs will be validated against the following display machine data:
MD9203 $MM_USER_CLASS_WRITE_FINE (defines the access level)
MD9451 $MM_WRITE_ZOA_FINE_LIMIT (possible input values)
The base work offset (base WO) is displayed like a settable work offset and can be selected
and modified using the "Base WO" softkey in the screen form "Overview of work offsets".
