Significant cleanup to how configuration files are generated.

Default autogenerated version works. Need to sort out config options

+# Checklist for correct CML2
+# 1) Have you defined a prompt for each menu, choice_type?
+# 2) Have you defined a default for each symbol?
+# 3) Have you put 'symbols' keyword before each symbol, menu and choice?
+
+
+# Important note on derived symbols
+# DO NOT place any declaration for derived symbols like normal symbols,
+# otherwise the derivation will be silently ignored, and you will be left
+# wondering why.
