clean up default config a bit

- HT Les Burrows for the suggestion/bug report
I think there is a lot that could be changed around this, but I went for balance.  Firstly it switches to a default path of "HOME", takes out the ifdef "MAC" (sorry, other devs can support older platforms better than I, this is old MAC, not the modern OSX version which is supported).  It uses a dot file.  A lot of these changes could be minorly controversial as they change the behavior somewhat.  I think proper documentation, flags, and more cleanup around all of this would help.
