Fix serialization of Python breakpoint commands.

CommandData breakpoint commands didn't know whether they were
Python or Command line commands, so they couldn't serialize &
deserialize themselves properly.  Fix that.
I also changed the "breakpoint list" command to note in the output
when the commands are Python commands.  Fortunately only one test
was relying on this explicit bit of text output.
