to change the enable/disable status of other parameters worked fine for
the text mode interface but poorly for the wxWindows gui. So I
implemented it a different way. Now in every boolean parameter, there is
a field called dependent_list which is a list of parameters which
are enabled/disabled by that boolean. Having this list available
allows both the text mode CI and the wxWindows CI to know which fields
should be enabled and disabled as a result of a boolean changing value.
- when the set() method of a bool param is called, or when the
dependent_list is changed, a private method called update_dependents()
changes the enabled status of all dependent parameters.
- add macros to get parameter ids of serial and parallel port parameters,
using the port number as an input variable.
