fixes for build issues

The post-build copy of the compiled help file didn't work for me, and nlist.data.txt was missing.  I recovered that file from a CiderPress 3.0.1 install and fixed the post-build with a batch file.  See [comp.sys.apple2](https://groups.google.com/d/msg/comp.sys.apple2/wEIcrBt80b4/3AwfWcO_a8AJ) for more details.
