dynamicCode: Put code entries on a list

The dynamic code functionality has been generalised so that the names of
the code entries in the specifying dictionary can be set by the caller.
This means that functions which utilise dynamic code but use different
entry names (e.g., codedFunctionObject uses codeExecute, codeEnd,
etc..., instead of code) now function correctly. The differently named
entries now form part of the library hash, and re-building triggers
appropriately as they are modified.
